Chemistry laboratory has three principle activities:
The first activity is the analysis of a sample meaning that the physical properties of a sample can be determined using a large quantity of techniques like the measurement of pH, density, viscosity, UV/Visible spectrophotometry, Infra-Red spectrometry. The quantities of chemicals can also be determined in a sample and this while using highly precise equipment such as Head space/gas chromatography and HPLC using UV/Vis, Conductimeter and Evaporative Light Scattering Detector
During stability studies physical (pH, density …) and chemical (titration of active substance) characteristics can be determined of the product that is placed in stability. These products are analyzed regularly in time and are placed in certain conditions of storage (temperature, humidity …). These tests are done to simulate the different condition that a product can meet in its life.
The last of are principle activities is the development of new analytical methods. New product or new active substance need to be quantified. Chemistry laboratory develops using the right equipment and validates the analytical methods. A method which is validated is repeatable, linear, robust and precise and guaranties the exactitude of the results.
