Troubleshooting High Ion Chromatography Results in Electronics Manufacturing
Dr. Adam Klett, Director of Science at KYZEN Corporation, discusses troubleshooting high ion chromatography (IC) results in electronic manufacturing (previously discussed in this earlier video).
He outlines three possible scenarios: misinterpreted data, sample contamination, or actual high contamination levels. Dr. Adam recommends first checking the raw chromatograms for issues like baseline shifts, missing peaks, or poor resolution. He then advises verifying the calibration curve’s accuracy. If the system appears fine, he suggests investigating potential accidental contamination sources, including gloves, pipettes, extraction bags, and solvents.
Dr. Adam emphasizes the importance of running control samples and handling parts minimally during testing. If high values persist after addressing these factors, he recommends testing handling surfaces and materials that contact the product to identify the contamination source. This systematic approach helps manufacturers accurately diagnose and address ionic contamination issues in their electronic products.
