Abstract
<PICT:0922410/III/1> <PICT:0922410/III/2> Apparatus for estimating gases occluded in a metal sample (e.g. hydrogen in steel) comprises a loading device (6) by means of which the sample is introduced into an oven (7) with only a negligible amount of air, a channel (including the oven) to guide a carrier gas (e.g. argon) over the sample in the oven and a device (8) to measure the thermal conductivity of the resulting gas stream. The numerals relate to Fig. 1 in which the carrier gas is supplied through a needle valve 2, U-tube flowmeter 3 and drying agent 40 (magnesium perchloride) to the loading device 6 shown in detail in Fig. 2. The sample 50 is loaded into a tube 49 for heating in the furnace and the device 8 is a katharometer giving an indication on recorder 11 in the form of a figure corresponding to the instantaneous concentration of evolved gas in the carrier or in the form of a trace on a chart. The apparatus is calibrated by means of standard amounts of hydrogen introduced from gas burette 16 controlled by a diaphragm valve 23. The loading device (Fig. 2) comprises a hollow brass cylinder 31 to which carrier gas is admitted at 35 and which is open at the diametrically opposite side to permit the sample and carrier gas to enter the tube 49 (Fig. 1). The cylinder 31 contains an inner cylindrical block 30, rotatable therein and having a chamber 32 to which the sample may be admitted when in the position shown by removal of a stopper 37 in the cylinder 31. There are openings in the lower part of the block and in the stopper by means of which carrier gas can flow through the chamber as shown. By rotating the inner cylinder clockwise through 90 degrees and tilting the apparatus, the sample 50 can be placed in the position shown in Fig. 1 and carrier gas passed thereover without admission of air. If analysis of occluded gases is required, a molecular sieve column may be inserted into the apparatus.
