MQuant® (MQ) test strips can be considered as a mobile laboratory on a few square millimeters of plastic strip. As a screening method they provide the user with a rapid overview of the situation, which helps in making the choice of what, and perhaps if, further analysis is required, thereby leading to potentially substantial savings in time and analytical resources. The strip is a biologically-degradable polyester foil and the low reagent content, in the reaction zones, assists problem-free waste disposal.

The Merck TLC sprayer allows derivatisation reagents to be sprayed homogeneously onto developed chromatograms. It is equipped with two different spray heads, (0,8 and 1,25 mm), that are optimised for low and high viscosity solutions respectively. The electro-pneumatically operated sprayer uses compressed air-driven by accumulator power and inductive charging.

Purospher® RP-18 is designed for the separation of problematic basic compounds with simple neutral eluents. In addition Purospher® RP-18 allows the separation of hydrophilic compounds with aqueous mobile phase. Purospher® RP-18 is based upon a high purity, metal-free silica. The multi-step chemical modification and deactivation of the surface, and the polar endcapping, enables a peak-tailing-free elution of basic and chelating compounds. Purospher® RP-18 is not suitable for the separation of acidic compounds. The good chemical stability of Purospher® RP-18 enables the use of mobile phase conditions at pH 8 for a long period of time.
