The Sherwood Scientific Model 420 Clinical Flame Photometer was developed from the Single Channel Model 410 Flame Photometer with the objective of improving productivity and analytical performance when measuring sodium and potassium. It is available in Clinical (475 42 000) or Industrial (475 42 100) format with appropriate NIST traceable calibration solution concentrates. The biggest improvement is Dual Channel operation, allowing both sodium and potassium to be calibrated, measured and displayed simultaneously. The Model 420 retains many of the Model 410′s attributes: ease of use, ease of maintenance and stable flame design but is enhanced with auto flame optimisation, internal…
For clinical samples, Flame Photometry is the most sensitive and robust method for the determination of sodium, potassium and lithium. Sherwood Scientific’s Model 410 Clinical Flame Photometer is delivered with Na, K and Li filters pre-fitted and an appropriate multi-element calibrator in mmol/l (1 x 100ml). The instrument is also fitted with a digital interface and sodium linearization facility allowing direct, straight line calibration of clinically significant concentrations of sodium, as well as potassium and lithium, following suitable dilution. The Model 805 Continuous Flow Diluter, used together with the Model 410 Clinical Flame Photometer, gives nominal sample dilution ratios of…
The Sherwood Model 926 Chloride Analyser is used for the determination of Chloride Ions (Cl-) in both human and animal food products, agriculture, cement, gypsum and the pharmaceutical and water industries. Sample preparation is minimal for most products with running costs of approximately £0.20/test. The Sherwood Model 926S is used in clinical laboratories, generally for sweat test analysis on infants. It is calibrated at 100mmol/L. Sample size for this application is user selectable at 20ul or 100ul.

Urea is an organic compound that plays an important role in biological metabolism processes. Besides its physiological properties, synthetically synthesized urea has become a very meaningful compound in the clinical, pharmaceutical, and chemical industries. It is a starting material for the synthesis of a large number of chemicals including hydrazine and melamine that are further used for the production of resins eventually used as building materials. In agriculture, urea is a preferred compound to be used as fertilizer because of its high nitrogen content. Another application with constantly rising importance is it use as an active ingredient in exhaust gas…
