Elemental Analysis & Optical Rotation

The standard analytical services provided to the scientific staff of the IOCB include elemental analysis, optical rotation measurement of organic compounds and some other analytical determinations using volumetric analysis or ion selective electrode. If we can be of assistance with your analytical problems, please contact us!

Elemental analysis of organic compounds (EA)

The laboratory provides analytical capabilities for measuring content of hydrogen, carbon, nitrogen, fluorine, chlorine, bromine, iodine, phosphorus and sulphur in organic compounds. An automated CHN analyzer (PE 2400 Series II CHNS/O Analyzer) is used in C, H and N mode. The determination of other mentioned elements is based on volumetric methods, fluorine is determined by use of ion selective electrode.

Measurement of optical rotation / specific rotation (OR)

The ordinary optical rotation of plane polarized light can be measured in the UV/Vis range at six different wavelengths (365 nm, 405 nm, 436 nm, 546 nm, 589 nm and 633 nm) using the polarimeter Autopol IV. The sample cells for 0.5, 1.5 and 2.8 mL are available.
