Checking/Calibration
With circular polarimeters, the wavelength can change in the course of time due to aging. Therefore, regular testing and, if necessary, recalibration of the polarimeter is necessary. Sucrose solutions or so-called quartz control plates (QCP) can be used as test and calibration standards. This is possible because the optical properties (ORD) of quartz and sucrose solutions are almost identical.
Quartz control plates (QCP) are long-term stable test standards for polarimeters and are recommended by SCHMIDT + HAENSCH as test standards. For this purpose, 0.4 to 1.6 mm thin quartz disks are ground with the highest precision perpendicular to the axes and plane-parallel and installed in a stainless steel tube without tension. The sample space of SCHMIDT + HAENSCH polarimeters allows both the vertical displacement of quartz control plates and the free rotation (± 360 °) around its own axis. Rotation is the only way to determine whether the plates are tension-free and enable the polarimeter to be checked in accordance with the implementation regulations (SPS) of international standards such as ICUMSA and OIML.
With the Schmidt + Haensch software (AQUISYS 2008), the polarimeters of the Polartonic series meet all requirements according to CFR 21 Part 11.
