Why work with us?

LoGiCal reference materials are ideal for calibration and control in the measurement of drugs, metabolites and related substances. Specified and produced by experts, our solutions are produced under the rigorous quality assurance standards of ISO 17034 and will satisfy many of the requirements of your accreditation and professional bodies.

All our reference materials are accompanied by comprehensive certificates of analysis. These provide a full description of the material to which they relate and summarise the analyses undertaken during the characterisation process, so you can be confident in the robustness and precision of your results.
