Benchtop Inductively Coupled Plasma Mass Spectrometer

The HP 4500 is the first benchtop 1CP-MS. it has a new type of optics system that results in a very low random background and high sensitivity, making analysis down to the subnanogram-peMiter (parts-per-trillion) level feasible. It can be equipped with HP's ShieldTorch system, which reduces interference from polyatomic ions, Inductively coupled plasma mass spectrometry OOP-MS) is an analytical technique that performs elemental analysis with excellent sensitivity and high sample throughput, The...

Shmoo Pot Shapes

A shmoo plot is a graph that represents how a particular test passes or fails when parameters like frequency, voltage, of temperature are varied and the test is executed repeatedly The shape of ihe fai ng region is meaningful and helps in determining the cause of the failure. Shmoo plots typically fall into familiar categories with descriptive names A shmoo plot of normal circuit operation shows better high-frequency performance as supply voltage increases, as shown in Fig la However Otter...
