    TF-100 storage and chemical names question

    Hi,

    I read the notes about keeping the TF-100 kit out of the hot/humid weather so the reagants last longest. Is it okay that I am storing it in my fridge? I hope so, because it's been in there the past 5 days or so.

    My other question is can someone list what each of the R-#### reagants actually are chemically? I am a chemist and I'd prefer to know what I'm handling rather than some trade name.

    Thanks,

    Bill

    I think it is recommended not to store in your fridge. The main reason being every time you take it out,that is a large temperature swing which can shorten their life. The actual effect it has I don't know.

    Check out this page, in the notes section of each post, some but not all have their chemical name listed. http://www.troublefreepool.com/exten...ns-t25081.html

    The MSDS sheets are available at Taylortechnologies.com

    The fridge is not the best place for your chemistry for the reason mentioned above.

    Thanks for the tip. I'll find somewhere better to put it.

    MSDSs still aren't much help in some cases.

    CYA reagent = 99% DI water, 1% mystery ingredient.

    The MSDS is the only info available to me. Please call Taylor Technologies to see if they can provide what you need.

    Bill,

    I can tell you the standard components of the tests since they are mostly standardized tests so there is no secret in that. There are additional chemicals added for stability and other purposes and those will be proprietary. I suggest you look at the Hach paper "Current Technology of Chlorine Analysis for Water and Wastewater" for some useful information regarding the chlorine tests.

    R-0004/R-0014 Phenol red pH indicator dye (different concentrations for sample size); also contains a mix of proprietary chlorine neutralizers (not thiosfulfate)
    R-0600 Orthotolidine (OTO), chlorine indicator dye (TF-100 only, not K-2006)
    R-0870 N, N-diethyl-p-phenylenediamine (DPD), powdered indicator dye plus phosphate buffer, EDTA and organic acid
    R-0871 Ferrous ammonium sulfate (FAS), titrant reagent; usually modified for stability as with Ferrous Ethylenediammonium Sulfate (FEAS)
    R-0003 Potassium iodide, DPD Reagent #3 used for combined chlorine (CC) test (or Total Chlorine test in some kits)
    R-0005 Hydrochloric acid, acid demand reagent (K-2006 only, not TF-100)
    R-0006 Sodium hydroxide, base demand reagent (K-2006 only, not TF-100)
    R-0007 Sodium thiosulfate, chlorine neutralizer
    R-0008 Bromocresol green and Methyl red, Total Alkalinity (TA) indicator combination dye
    R-0009 Sulfuric acid, for TA titration
    R-0010 Sodium hydroxide, Calcium Hardness (CH) buffer (precipitates magnesium hydroxide to test only calcium hardness)
    R-0011L 1-(2-Hydroxy-1-naphthylazo)-2-naphthol-4-sulfonic acid sodium salt (Calcon), Calcium Hardness (CH) indicator dye
    R-0012 Ethylenediaminetetraacetic acid (EDTA), Calcium Hardness (CH) titrating reagent
    R-0013 Melamine, Cyanuric Acid (CYA) reagent; usually has pH buffers to force low pH; forms melamine cyanurate in the test
    R-0630 Potassium chromate indicator chemical for chloride salt test (forms red silver chromate)
    R-0706 Silver nitrate titrating reagent that precipitates silver chloride

    As a general rule, the indicator dyes are the least stable as they are organic dyes. The FAS reagent is also less stable and also sensitive to light. The strong acids and bases will last essentially forever while the other chemicals last somewhere in between (potassium iodide, EDTA, sodium thiosulfate) mostly dependent on their exposure to oxygen in the air. This link from Taylor may be helpful to you in recognizing a compromised reagent.

    Since you are a chemist, it would be great if as you peruse the site and run into the technical posts, especially in The Deep End, if you would correct anything you see that might be wrong or incomplete. Just ask in the appropriate thread or if it's something I've written and you don't want to post, PM me. Welcome to TFP!

    Could you please add R-0630 and R-0706?
