The ChemCal chemical printer and mapper is an instrument that can generate precisely known concentrations of single or multiple chemical compounds on smooth or irregular surfaces. This provides well defined chemical targets for calibrating detectors used for measuring the type and concentration of trace chemical contaminants on surfaces.
It can handle as many as 22 different chemicals, which can be laid down on both smooth and irregular surfaces in a variety of nanodroplet patterns, which are interleaved or overlaid to suit the chemical detection application. Colloidal dispersions, such as microbial dispersions can also be accurately deposited. In addition, it can handle a wide range of fluid viscosities and surface tensions.
The advantage of ChemCal chemical printer and mapper over other multi-nozzle inkjet array methods is that it can deposit highly accurate concentrations of materials in both uniform and non-uniform concentrations or gradients to simulate situations in which trace contamination detectors are employed.
