PARR - The 1108 Oxygen Bomb with a Quartz Liner for Determining Trace Elements in Combustible Samples

Trace elements in coal, oil and other combustible samples are readily determined by AA or ICP spectroscopy following combustion in an oxygen bomb. However, trace amounts of heavy metals leached from the bomb walls and electrodes during combustion can cause problems. This can be avoided by using a platinum-lined bomb, but a platinum lining is expensive. As an alternate, Parr offers a quartz liner for the 1108 bomb which does not provide the full protection of platinum, but is, nevertheless, an effective substitute. In this arrangement the burning sample comes in contact with only the quartz liner and platinum electrodes. Reprints of papers describing the successful use of an 1108 bomb with quartz liner for trace analysis by AA spectroscopy are available from Parr.

The Quartz Liner The quartz liner for the 1108 bomb consists of a quartz cup, 61 mm dia. x 86 mm deep, with a flat quartz cover. Holes are provided in the cover for inserting platinum electrodes which support a fused silica sample cup and a short platinum fuse wire. All of the parts needed for adding this liner are provided in the 1912 Quartz Liner Conversion Set, consisting of: 1x 513A Quartz liner 1x 514A Quartz liner 1x 4AFB Platinum electrode 1x 5AFB Platinum electrode 2x 68AC Lock nut, T303SS 1x 45C3 Platinum fuse wire, 300 cm 4x 43A3 Fused silica combustion capsules
