General & Wet Chemistry

Training in both gravimetric and titrimetric techniques, together with colorimetry, is a requirement of all analysts within Butterworth Laboratories. This enables all the analysts to perform a wide range of basic qualitative and quantitative tests such as those found in the Pharmacopoeias and other published methods, in addition to specific instrumental techniques.

Given the importance of these applications, Butterworth continues to employ staff dedicated to classical chemistry analysis. When macro analysis (the determination of quantities of 0.1g or more) is being undertaken, these classical analytical chemistry techniques can often provide much better relative precisions than the more modern instrumental techniques.

Instrumental Techniques available include:

• Range of 1, 2, 3, 5 and 7 figure balances
• Range of incubators, ovens & furnaces
• Potentiometric titrator
• Colorimetric & conventional Karl Fischer titrators
• Ion Selective Electrodes
• UV/VIS spectrophotometers
• Microwave digester (Acid Digestion and Solvent Extraction Capabilities)
