Abstract
A rock analyser includes a chamber containing a heater (2) and the sensor (6) of a hydrocarbon detector (7), the heater (2) being connectable to a source of power (5) and the sensor (6) being connected to the remainder of the hydrocarbon detector (7). The analyser determines the amount of hydrocarbon material present in the rock. It is portable and is useful for field screening tests to reduce the number of samples sent for laboratory analysis.
Claims4
A portable analyzer for determining the amount of hydrocarbons present in a rock comprising:
- a chamber for holding a rock sample to be analyzed;
- heating means within said chamber for heating the rock sample so as to drive off, without combusting, hydrocarbonaceous material present within the rock sample, said heating means having contact means for electrically connecting said heating means to a source of power;
- detecting means for detecting the amount of hydrocarbonaceous material driven off from the rock sample by the heating means, said detecting means comprising sensing means within the chamber and recording means outside the chamber electrically connected to the sensing means.
