WebHPLC Grade, LC/MS Grade There are many considerations when using water intended for chromatography applications (HPLC, GC, IC) as they must be free of ... particles, or bacteria can all affect the separation process and/or result in ghost peaks. Applications for HPLC Water and trace metal analysis require water conforming to highest purity ... Webinstrumentation cost is low. The HPLC method is able to differentiate between chlorophyll types and accessory pigments, but is a slower and more demanding technique, e.g. 20-25 minutes of sample processing time. The cost of an HPLC instrument may be 10 times the cost of a spectrophotometer, and there are considerable ongoing consumables costs.
