Laboratory evaluation of the Greiner G450 discrete analyser

Evaluation of continuous and discrete melting endotherms in determination of structural heterogeneities in Ziegler-Natta catalyzed linear low density polyethylene

Ethylene / 1-butene copolymers at different comonomer levels were synthesized using Ziegler-Natta catalyst to evaluate the applicability of thermal fractionation methods in predicting chemical composition distribution (CCD). The continuous melting endotherms by DSC were converted to continuous CCD, and the average comonomer contents were compared with NMR results. DSC underestimated comonomer c...

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 diff...

A clinical appraisal of the Greiner G300 clinical chemistry analyser

Evaluation of the Kodak Ektachem DT60 analyser for sodium, potassium, glucose and urea

The Kodak Ektachem DT60/E analyser is a desk-top analyser which uses thin-film ’dry’ chemistry technology to perform colorimetric and potentiometric analyses. The analyser is simple to operate and the slides are claimed to be stablefor up to oneyear if stored at 4 C. Calibration is said to be required only once every three months. Results presented in this paper substantiate these claims and sh...
