ClinCal® Calibrators are designed for the calibra­tion of the analytical system (HPLC, LC-MS/MS, photometry, etc). The analytes of ClinCal® Calibrators are available in matrices (urine, plasma, serum, whole blood), which are comparable to those in patient samples.

Basically these calibra­tors are prepared in the same manner as the patient samples during sample preparation; this way problems caused by matrix effects can be widely excluded. In contrast to the use of a directly injec­ted matrix-free standard solution, systematic fai­lures during sample preparation are compensated with this procedure. RECIPE ClinCal® Calibrators are establishing the basis for the accurate determination of your analytes.
