Optmising ICP-MS analysis of difficult samples is made easier, particularly in large batches which are run overnight, by this innovation from PerkinElmer An end to recalibration? In laboratories where productivity is important, it may be necessary to run sample batches overnight.
Quality control software may initiate re-calibration because of instrumental drift, slowing down the process of sample analysis.
Deposits of sample material during ICP-MS analysis of complex sample matrices are a common and troublesome cause of drift.
PerkinElmer's computer controlled Elan 6100 ICP-MS is designed to accommodate unattended analysis of the most difficult samples, with particularly large interface cone orifices and protected ion optics.
An application note from PerkinElmer outlines a method of establishing the best operating conditions for maximum long-term instrument stability. The note describes instrument conditioning procedures and sampling methods.
Results are given for an eight-hour batch analysis of rock fusion samples, without re-calibration and compared for instrument drift with the results of a 15-hour batch analysis of a water matrix, also without recalibration.
