    Polarimeter is an instrument used for determining optical rotation of substances. It is also used for measuring specific rotation, concentration & international sugar scale of optically active substances. Polarimeter is ideal for pharmaceutical, food and beverages, sugar, cosmetics, oil refinery, chemical industries & also scientific research studies.

    CONTECH Digital Polarimeter is a fully automatic instrument and eliminates the need for manual adjustments thus offering a high degree of measurement precision.

    The polarized light after passing through the sample falling on the analyzer deviates from the optical zero position to the extent of optical rotation of the sample and the photomultiplier detector will produce an electrical signal with the frequency corresponding to the optical rotation of the sample. This signal after passing through the selective frequency circuit and power amplifier drives the servo-motor & in turn the analyzer until the optical zero position is regained. The analyzer rotation is measured by an encoder and is displayed on the digital readout as the optical rotation of the sample.

    XRF is used to detect and analyze noble metals like Gold ( Au), Silver (Ag), Platinum (Pt),Iridium (Ir), Osmium (Os), Palladium (Pd), Rhodium (Rh), Ruthenium (Ru), Copper (Cu), Zinc (Zn), Nickel (Ni), Cadmium (Cd), Iron (Fe), Cobalt (Co), Indium (In), Tin (Sn), in the Jewellery Industry.

    Energy Dispersive X-ray Fluorescence (EDXRF) technique relies on the detector and the detection circuit capability to resolve spectral peaks due to different energy X-Rays emitted when a primary X-Ray beam strikes a metal alloy corresponding to different elements in the sample, intensity of the spectrum radiation proportional to the concentration of element. The spectrum is then processed through the powerful computer software which calculates and reports the various elements & their composition in the sample.

    XRF Gold Purity Tester consists of X-Ray tube, high voltage power supply for X-Ray source, X-Ray tube filters, X-Ray fluorescence Detector, processing electronics and system interface & an external computer. A camera is incorporated in the system to view the sample on the computer screen.
