Test Kits for Etch Lines
2005
Our company uses a number of etch products from the old Diversey Wyandotte company. Unfortunately, the old manufactures of the etching products used to supply test kits to monitor the solutions, and now they do not. I am trying to reproduce the test kits for our etch line operators to monitor the solutions real time.
Therefore my question is; Does anyone know or can anyone recommend a source for getting the information from which these test kits were made? For example if I were testing a solution of Aluminux 1000, the instructions state to use "Solution #18" and to use "one Dropper" sample size. What chemical(s) make up Solution #18 and how many mls equals one dropper?
Thanks for your interest and help.

Ask the manufacture for a control sheet. they will give you a laboratory procedure. With this, go to a company such a Hach for suitable test materials. I will bet a Starbucks if you send a copy of the lab tests to Hach with a polite request for help, that they will send you back a complete procedure to use with their products. Short of that, set up a mini lab.

Tell your new supplier to provide a kit for you or you will change suppliers, that will get em moving :)
As for the drop size it depends on the dropper! you could determine this yourself with a bit of DI water and an accurate balance. remember the density of pure water is 1 gram per ml. So place 10 drops into a dried beaker [beakers on
eBay
or
Amazon [affil links] then divide the weight by 10 and you will have the average volume (ml) of 1 drop.

Asking your supplier as a requirement for the test kit might just work if you are a large enough user. If not, contact Kocour Chicago IL. Describe your need and they generally sell a packaged analytical kit with all the chemicals and glassware with instructions.
