Posted: Fri Feb 20, 2009 5:09 pm Post subject: Filtering EICS. |
|
|
I just want to know if anyone can offer information on filtering EICS?
I have recently read an article on Luer-Lok syringes, which take a ceramic filter, and believe they would be suitable for determining silver particle size. Yes, I know all about lab tests etc as I have had several samples of mine tested, but they failed to report particle size as I requested, got everything else, just not particle size, and I have to say that my test results have put a very different slant on most of what I have researched over several years in the public domain as well.
What they did state is the paper filter size the particles *failed* to pass through, but that doesn't give me a particle *size* necessarily.
I have read these syringe filters will filter down to 1 micron, but I want to know if they filter smaller than this, if not, then I'll forget the whole idea. Personally, I believe they would be ideal, providing they filter less than 1 micron. With this information then I will have the final part of my tests complete. |

Hi Ino...
An intriguing idea. Doultan has ceramic filters that are certified 100% to filter particulates down to 0.9 microns. I'm certain that comparible technologies would offer.
In fact, the luer-loks are used by the Center for Nanoscale Chemical-Electrical-Mechanical Manufacturing Systems:
http://www.nano-cemms.uiuc.edu/content/education/online_labs/01/index.php
However, also realize that any type of filteration has been shown to effect EIS. The act of filtering can cause agglomeration... However, I'm not certain that a purely ceramic filter has ever been used and tested.
Kind Regards, |

Thanks Jason,
Well it seems you have raised a good point here, regarding agglomeration. I have not read, or taken that into consideration before. If that is the case, then it would be rather difficult to determine, with a definite degree of accuracy, the silver particle size. I have done some limited research into particle ‘shapes’ and have found that this is determined after the silver is dried, which will probably be different to ‘wet’ particle shapes also, if you understand, but I’m digressing.
If you don’t mind Jason, I would like to pass on just one of my test results to you and invite any comments you may have. My results seem to be far different to what is available in any published material I have read thus far. I’ve been producing EICS for a number of years for personal use and application, and am still ‘experimenting’ in one way or another.
Sample 1
Clear solution…(after 18 day stabilising time frame).
Soluble Ag - 12.0mg/l…(filtered through 0.45 micron paper filter).
Total Ag – 23.5…(acidified HCL).
%ionic/%particulate – 51/49.
Solids – 5.0mg/l…(filtered through 0.45 micron paper filter).
Theoretical insoluble Ag – 11.5mg/l.
pH – 7.4
Conductivity – 23
You can already see that ion/ particle ratio is far different than that found in any published material I have read, and I have read just about all there is to be read on EICS <grin>.
Remember though that this solution was a ‘clear’ solution and my best method of determining suitable quality of my EICS is using my eyesight, ie; if there is *no* visible settlement, or ‘fall-out’ of silver in the container then I consider this to be a very good product, and this is what I aim for. I have always assumed a stable solution with no settlement is the best possible.
Now, 0.45 micron equates to 450nm which suggests the particle clusters are a little large, going on what is available in the public domain that is, but I am having to reconsider, or re-evaluate most of what I have read and researched going on my test results.
I’ve had 4 samples tested…clear, yellow, amber or ‘tea’ colour, and a clear solution produced using a 4 electrode setup, and going on lab results I am having to reconsider, or re-evaluate published material on EICS ‘colour’ available in the public domain as well. I maintain that unless everyone around the world uses the exact same setup, and produce EICS under the exact same environmental conditions as material published, there would be quite a considerable difference in the EICS produced. I could be wrong there, but my results tend to support that assumption.
If I knew more about those syringes I spoke of then I could determine the particle cluster size myself, well, near as damn it anyway.
I’ll check that site out you quoted also.
P.S. I have just realised that your 'agglomeration' statement could answer my question regarding particle cluster size, Thanks for that!
P.P.S. Just looked at that site...this is in fact where I got the idea about syringes and filters!! |

Hi Ino:
That's definately very interesting test results.
I'm assuming, based upon both the conductivity and the end PH, that you are not using the HVAC method of production in this case; I'm also assuming you are starting with a distilled water that is very pure, and close to a ph of 7.
If my assumptions are correct ( and please correct me if I am not ), then there is only one other explanation I have for your unique results.
Can you tell me what happens if you add a drop of 35% H2O2 to four ounces of your EIS?
Color changes, cloudiness, and especially what exact changes can be seen via the Tyndall effect ( before and after ).
Thanks, this is very interesting!
Kind Regards, |

Jasons’ snipped quote:
[I'm assuming, based upon both the conductivity and the end PH, that you are not using the HVAC method of production in this case; I'm also assuming you are starting with a distilled water that is very pure, and close to a ph of 7.]
-Yes, I forgot to mention that, I’m using LVDC and distilled water. As for the ph, I’m sorry I can't say, I only check the ppm of the water before I start production with a Com 100 meter set on KCLppm and a Hanna TDS 1 meter, usually it’s 1.0 - 1.1 and 001 respectively. Having said this however, since my test results I am now noting KCLuS and KCLppm with each batch, I am also starting to note water temperature…I produce 1 litre at a time.
[Can you tell me what happens if you add a drop of 35% H2O2 to four ounces of your EIS?]
-I don’t have, (and pharmacies where I am located will not assist me), the 35% HP, I’ve only got the over the counter 3% and 6%. I have researched this to some degree also and have ‘tentatively’ leaned to a conclusion that the lower percentage peroxide should be adequate for ‘testing’ purposes. Don’t get me wrong here though, and I stand to be corrected of course, but as I am unable to get any assistance from pharmacies I must do the best I can. I have had it said to me that to ascertain the amount of additives which may be present in the lower percentage peroxide, is to put some in a clear glass container and leave it out in the sun for 24-48 hours, (covered), and observe bubbles which may become evident, the fewer the bubbles, the less additives.
I have only done the peroxide test once and threw it away as I have yet to learn more regarding peroxide and EICS, (one step at a time scenario, I wanted to get this right before moving on to that next step). I believe I used a small amount of the ‘tea’ coloured solution and used 3 drops of 3%…solution went black, (which apparently is normal), used a further 5 drops and as it remained black I threw it out. This is something which I have yet to experiment with further as I have since learnt that *time* is required for the peroxide to break up the particle clusters which may be present. Apologies for my ignorance when it comes to peroxide, I need to learn a *lot* more about this aspect yet so am not familiar enough to pass any comment or offer any help in this regard.
[Color changes, cloudiness, and especially what exact changes can be seen via the Tyndall effect ( before and after ).]
-I can only say that in the tested solution in discussion here the TE was faint, and remained unchanged from completion of production to time of testing…18 days. I can’t say anything regarding peroxide for the reasons quoted above, sorry. Oddly enough I can get another solution which is clear but have a stronger TE. I’m working on an understanding of why this is so at the moment. I believe it’s the switching of electrodes at a particular interval that alters this.
May I add here that your ‘agglomeration’ statement has really made me re-think the whole issue of particle size, see, nobody has ever mentioned the ‘agglomeration’ of silver when filtering. I can see that this is absolutely correct, how dumb of me not to consider that before. Effectively, this would mean it is going to be *very* difficult to determine *actual* or *real* size of particle clusters *while still in solution*. This would incorporate some form of ‘wet’ test I spoke of earlier, and I know of no ‘wet’ test for EICS particle content. I can’t believe how obvious this ‘agglomeration’ result when filtering is since you’ve mentioned it, and can see that even the syringe idea would probably not work either. My eyesight analysis for any observable settlement is looking better all the time <g>.
Your simple response to my request for information Jason has been an absolute revelation to me. You have made me understand now that the 0.45 micron filter used in my tests really has little relevance to *actual* size which the silver particle clusters may have been *prior* to the filtering process. That’s really interesting! Either people haven’t considered that, or they just don’t divulge that information.
Cheers. |

Hi Jason,
As I don't observe settlement in the bottom of my containers perhaps you could tell me the purpose for which you would use H2O2. Correct me if I am wrong, but isn't that just used so as to return silver particle clusters back to an ionic state?
If I have nothing falling or settling out of solution then I don't see a need for this. Ions are obviously present, and any particle clusters which have formed are not of a size large enough to 'fall' out of solution. Could you let me know what purpose H202 would serve in this instance.
I probably should add that I keep any buildup on electrodes to a minimum by cleaning at regular timed intervals during production process.
As I stated earlier, I am somewhat surprised at the ion/particle ratio, while at the same time not observing any settlement. This is the main thing I seek some opinion on, almost a 50/50 ratio and nil fall-out! Could it just be that my production procedure is efficient, and I simply prevent any potential 'fall-out' situations by this procedures I have developed? If I prefer a high ionic content then all I have to do is make a much smaller amount and ingest it...'within a matter of hours' lets say, which minimises the time needed for more particle clusters to form, or existing ones to get larger, the way I see it is I have a choice, and have suitable control over what I produce for the purpose I want to use it, ie; higher ionic content or a more 'balanced' ion/particle content.
I would be content of course if there is no explanation for it, I am happy with that scenario. I am of the opinion that the magnetic stirrer I made is a major contributing factor which influences my results.
Cheers. |
