Where is a bomb calorimeter used?
Our calorimeters are widely used in all industries; it is just not a common type of instrument. A calorimeter has affected every one of our lives in some way, which is quiet a statement. From the food we buy on the shelves...

How to prepare various sample types
Generally approximately 0.5g of a sample is weighed into the crucible, the cotton thread is attached to the wire, and the crucible is put into the vessel. This applies to powdery substances. But what about other substances?

The use of Benzoic Acid in Bomb Calorimetry
Although benzoic acid has many uses outside of bomb calorimetry, we will touch on the subject of its use in calorimetry. Benzoic acid is relatively non-toxic and occurs naturally in plants....

The Spiking Method in Calorimetry
What is spiking? If a sample does not ignite easily or not at all in a calorimeter, then the spiking method of ignition can be used to promote complete combustion of the sample...

Why choose a waterless calorimeter?
Most traditional bomb calorimeters make use of water to measure the temperature of the sample combustion within the calorimeter, but DDS Calorimeters have a different approach to this. We've removed the water component from the calorimeter, and here's why...

Solving or Preventing a Misfire using the CAL3K Bomb Calorimeter
A ‘Misfire’ is indicated by the calorimeter when the temperature has not risen above the ‘MISFIRE TEMPERATURE RISE’ limit 30 seconds after firing. This can have several reasons, which are explained....
