Labcell has introduced the Decagon Devices AquaLab TDL water activity analyser for use with virtually any solid, powder, paste or liquid.
The analyser features a tunable diode laser (TDL) for very precise measurement of water vapour in the headspace above the sample, hence unaffected by the presence of volatiles.
As well as being suitable for quality assurance and product development in the food, pharmaceutical, cosmetic and tobacco industries, the AquaLab TDL can be used for other applications, such as assessing aviation fuel for water contamination.
It can analyse products or ingredients containing the humectant propylene glycol, alcohol or soy sauce.
The AquaLab TDL gives readings with an accuracy of /-0.003 aw in approximately two minutes.
Built-in temperature equilibration ensures that readings are always consistent, verification is quick and simple by means of independent salt standards, and cleaning is easy.
