The laboratory has extensive experience in diagnosing and eliminating product and process contamination including cleaning, degreasing and subsequent rinse processes. It also offers practical recommendations of alternative methods.
Surface Analysis techniques in particular are ideal for tuning of cleaning and rinsing processes with their surface chemical sensitivity. Bath rinsing practices are critical as use of town water, insufficient rinse times or poor refreshing practices optimising against process product throughput. Poor practices can leave unwanted staining and contamination. We have an ideal range of surface analysis techniques that can help identify cleaning, degreasing and rinsing issues. These include: XPS, SIMS and AES / SAM coupled with SEM/EDX, GC-MS and FTIR. Tighter environmental and Health and Safety regulations mean that many industries are required to replace solvent based cleaning / degreasing processes with aqueous-based systems. Although aqueous degreasers are safer for operators, they tend not to be as effective: They leave remnants on the material surfaces, potentially affecting a component’s fitness for use or downstream manufacturing. The lab has extensive experience in the change over of solvent based cleaning / degreasing processes to aqueous and also of the problems this can lead to. We can work to isolate / identify contamination levels and offer elimination advice with optimised cleaning agent formulation, depending on our findings.
