In the laboratory where accuracy is everything, standard and controls play an integral role in ensuring results you can trust. A standard is a solution that contains a known concentration of a specific chemical or analyte and they serve as the reference point for the calibration of instruments, controls are used as the basis of comparison for various samples and solutions. They are available for numerous different analytes and also in many concentrations.
