Laboratory evaluation of the Greiner G-400 discrete selective multichannel analyzer

We evaluated the new Greiner G-400 selective multichannel analyzer. Thirty different tests can be run in combination profile and single-test mode at a rate between 150 and 300 tests per hour. The new photometer allows kinetic and equilibrium (endpoint) measurements. The G-400 analyzer demonstrated excellent precision, linearity, accuracy, ease of operation, and no carryover. Results for 16 different analytes as determined with the Hitachi 705, GSA II, and Corning 940 correlated favorably with those obtained with the G-400. The G-400 analyzer is suitable for both emergency and routine use.
