Additionally, the energetic content of the other three feed samples (1 g) was measured using a
microcalorimeter (IKA[R] C 200 and precision of 1 J [mg.sup.-1]).
The
microcalorimeter was frequently calibrated electrically during the experiment.
Other products provided by TA Instruments include rheological measurement systems,
microcalorimeter systems providing the ultimate in sensitivity, ruggedness and versatility, ElectroForce mechanical testing instruments for the dynamic characterization of a range of materials, thermal conductivity meters, flash diffusivity instruments, dilatometers, and a complete line of new instruments for the measurement of rheological and physical properties of polymers, rubber and rubber compounds at all stages of manufacture.
Calorimetric measurements were performed using high-sensitivity differential adiabatic scanning
microcalorimeter DASM-4 (Biopribor, Pushchino, Russia), with a sensitivity >0.017 mJ x [K.sup.-1] and a noise level < [+ or -]0.05 [micro]W.
[33] studied the effects of coal functional groups on the adsorption microheat of coalbed methane using a C80
microcalorimeter.
Figure 4 shows the
microcalorimeter manufactured by Tokyo Riko Corporation, which was used for measuring the microhydration heat.
A ratio of released and adsorbed heat of developed formulations was determined using microSC
microcalorimeter (Setaram Instrumentation, France).
