The RSD helps chemists and engineers quantify exothermic (and endothermic) reactions from materials of low hazard to high explosives.
The heated calorimeter chamber has a circular pathway to allow air (or inert gas) to circulate repeatedly during the test. The gas passes through the sample chamber and over the main heater. Circulation is achieved by a high temperature fan and a control thermocouple regulates power to the heater to implement the test protocol.
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.
