Micro‐Volume Injection System for ICP‐MS
The MVX‐7100 L Workstation when paired with a DS‐5 total consumption nebulizer creates a paradigm shift in ICP‐MS sample introduction. It is a long overdue tool for trace element researchers wanting to measure elements at trace levels in microliter sized samples. In this study the MVX‐7100 is used with quadrupole ICP‐MS for injection of 20 L and 100 L volumes.
When working with micro‐volume samples we have found that all aspects of sample introduction must be re‐ considered. Four critical parts are needed for repeatable results: (1) high precision probe positioning (2) discrete aliquot sampling (3) stable sample injection (4) low flow nebulization. The MVX‐7100 has been optimized for each of these critical parts with (1) encoder driven X, Y, Z autosampler able to sample 384‐well plates, (2) syringe driven sample aliquot, (3) syringe driven sample injection, and (4) DS‐5 total consumption nebulizer
