Limit Testing For Heavy Metal Impurities
Offered by Warwick Analytical Service as an analytical service, the limit test for heavy metals is a qualitative test that demonstrates that the content of metallic impurities in organic samples does not exceed the limit specified in the Pharmacopeia standards. Metals that respond well to the limit test are Lead, Mercury, Bismuth, Arsenic, Tin, Antimony, Cadmium, Silver, Copper and Molybdenum.
Asked about the limit test - Rebekah Vine (Laboratory Manager at Warwick Analytical Service) commented "Highly regulated companies, such as work in the pharmaceutical industry, not only are looking for testing to Pharmacopeia approved standard methods but also for a high level of compliance to QC procedures including better traceability on all data supplied". She added "The Heavy Metals Limit Test offers an inexpensive alternative to the ICP/MS Pharmacopeia method USP 730".
Operating in an ISO 17025 and GMP accredited environment, Warwick Analytical Service follows strict operating procedures whereby sample solutions are analysed against a 3-point calibration (10, 20 & 30ppm) of lead standard solution prepared the same day. A colour matching process is then used to distinguish whether the sample under the test conditions passes or fails the heavy metals limit test.
