Description

The American Optical TS meter model 10400 total solids refractometer has been designed for simple, rapid microanalysis in biomedical, chemistry and classroom laboratories. The determination of concentrations of solutions is one of the oldest uses of refractometry. The TS refractometer offers unprecedented simplicity of application, lending itself to checks and controls of many laboratory reagents, preparations, pharmaceuticals and specimens.

Scales are calibrated for protein concentration of plasma or serum (grams/100mL) and specific gravity of urine and refractive index determinations are precise and rapid and require only a drop of fluid sample. The value on the appropriate scale seen through the eyepiece, is read where the sharp boundary between dark and light fields crosses the scale. The instruments are temperature compensated for temperatures between 60°F (16°C) and 100°F (38°C). The reading does not need to be adjusted for the sample or ambient temperature.

The accuracy of the determination of total solids–or water–in plasma and urine from measurement of refractive index, and for the measurement of specific gravity of urine from refractive index, has been well documented. The estimation of plasma or serum protein concentration by refractometry has also been advocated for many years. The accuracy of this determination is satisfactory for clinical use although it is not as reliable as the measurement of total solids and of specific gravity.
