Magnesium-selective test strip.

A selective test strip based on an ion-exchange mechanism to determine magnesium is described. This optical and reversible test strip, made on a transparent polyester sheet, has a circular polymeric film of plasticised PVC that contains all of the reagents necessary to produce a response to magnesium, namely, a cation-selective neutral ionophore, 2-amino-N,N'-diheptyl-N,N'-dimethyl-butanediamid...

An assessment of the Azostix strip test.

The approximate concentration of urea in a single, unmeasured drop of blood may be estimated with an Azostix strip in a little over a minute, without the use of laboratory equipment. The test has been assessed by comparing 488 strip readings made by two observers on 331 specimens of blood from patients with plasma urea concentrations determined by the Auto-Analyzer diacetyl monoxime method. Obs...

Test Bench for Silicon Strip Detectors Testing

During the next few months more than 400 Silicon Strip Detector (SSD) modules will be tested before and after their installation on the ladders and dispatch to Brookhaven National Laboratory. The requirements for the test bench have been defined and the architectural design of all software components has been completed. The system is distributed and features a client–server architecture. Measur...

Test-strip method for measuring lactate in whole blood.

We have developed a dry reagent strip system for measuring lactate in whole blood. The test strip contains lactate oxidase (no EC number assigned), horseradish peroxidase (EC 1.11.1.7), and N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine. The system is designed to measure with a reflectometer the color that developed in the test strip, although the lactate concentration can be estimated without...
