Re: How do you test for Tin in a plating bath?We use a wet method for our tin-nickel bath. Our operating range in normally 0.5 - 0.75opg, so adjust your sample size and factor accordingly. 1.Pipette exactly 50 mL of hot sample into a 250 mL Erlenmeyer flask. 2.Dilute with approximately 25 mL of de-ionized water 3.Add 5 mL concentrated hydrochloric acid and two droppers of starch. Mix and IMMEDIATELY begin the next step 4.Titrate drop by drop (no faster than 1 drop per second) with .05 N potassium iodate to the very first drop that gives you a color change (purple or blue) mL Potassium Iodate * 0.03635 = oz/gallon of tin -Dustin Gebhardt, CEF Advanced Manufacturing/Finishing Engineer Moen Sanford, NC Re: How do you test for Tin in a plating bath?Is this for your cyanide bronze? If it is you better have some good ventilation when you add the hcl. There has to be a better way. You might need to check with Hach or somebody. Jim Re: How do you test for Tin in a plating bath?Yes it is with my cyanide bronze tank. Thank you for your response. I came across one something like that. Was hopping for a safer and easier way to do it.
