RAPID SCREENING DEVICE (RSD) is a technique which is primarily used for stability investigation of
different kinds of chemicals by safety researchers to quantify thermal hazards by the temperaturepressure-time and heat of reaction data obtained.
RSD uses sample quantity in grams to obtain more quantitative data than other conventional
instruments.
RSD has more advantage when it comes to sample testing which is equipped with six sampling
chambers which helps to test different kinds of samples (six samples at a time) or different stages of
desired product simultaneously which is time saving and which gives fast and reliable data.
The advantage of RSD over the DSC is that the thermocouple positioning, in RSD which is directly in to
the reaction sample where as conventional DSC uses pan-bottom approach to measure the heat from
the reaction due to that RSD can detect the low heat from reaction and which is clear accurate.
