Flame Photometry is the technique of choice for the measurement of sodium, potassium and calcium in all sample types for: • mineral extraction• oil industry• paper industry• pharmaceuticals• soil analysis• utilities• food and beverage• chemical manufacture• fertilisers Sherwood Scientific’s Model 410 Industrial Flame Photometer with digital output (for printer or PC connection), also offers sodium linearization capability to allow higher concentrations of Sodium (<40 ppm) to be directly measured using a single point calibration. This facility can be switched on or off according to the operator’s preference or protocol for sodium determinations. The Model 410 also has sodium, potassium and…
Sherwood Scientific have developed and manufactured a range of two general purpose Fluid Bed Dryers (FBDs): one analogue and one with digital controls of airspeed, temperature and time. In addition, Sherwood Scientific have also developed a programmable FDB where drying programmes can be created and stored on computers. BenefitsThe laboratory fluid bed dryer offers significant advantages over conventional drying techniques: • The high rates of heat and mass transfer ensure much faster and more homogeneous drying than other methods such as oven and vacuum drying.• Drying times range from a few seconds to minutes. Complete drying is usually achieved in…
Raw material identification or verification (of the packaging label) is a common quality-control practice. In the pharmaceutical industry, the increasing global footprint of the supply chain and public health concerns1 resulting from contaminated materials (or mislabeling) have driven many regulatory bodies to require inspection of every barrel in every shipment of materials used in the manufacture of pharmaceutical drugs. Handheld analytical instruments are becoming more common for rapid and non-destructive testing of incoming raw materials directly in warehouses, reducing the cost and time needed for taking samples to the laboratory and quarantining incoming shipments until lab testing is complete.
