Accessories

Parr offers a number of options and accessories for use with their Oxygen Vessels.

Combustion Capsules
43A Fuel Capsules

43A Fuel Capsules

Non-volatile samples to be tested in Parr oxygen vessels are weighed and burned in shallow capsules measuring approximately 1″ diameter and 7/16″ deep. These are available in stainless steel, fused silica, fused quartz, and platinum alloyed with 3% rhodium.

Stainless steel capsules (43AS) are used for most applications. When combusting samples that contain metal particles such as aluminum or magnesium, the non-metallic fused silica/quartz 43A3 Capsule or fused quartz 43A3KQ is required. When superior corrosion resistance is needed, the Platinum Rhodium 43A5 Capsule is required.

Ignition Unit
2901 Ignition Unit

2901 Ignition Unit

The 2901 Ignition Unit provides the proper electric current for firing a Parr oxygen vessel from a 115 or 230 volt line. Each carries a push switch, pilot light and output binding posts for connections to 7 or 10 cm vessel fuses. Connecting cords must be ordered separately.

Oxygen Filling Connections
1825 Oxygen Filling Connection

1825 Oxygen Filling Connection

These Oxygen Filling Connections provide all of the valves, gages and couplings needed for charging Parr Oxygen Vessels from a commercial oxygen tank under manual control. They are made in three styles that are identical except for the coupling on the vessel filling hose. All units fit a standard 1A oxygen tank having a CGA 540 outlet with a right handed thread. Two pressure gages are provided. The larger gage, graduated from 0 to 55 atmospheres, shows the pressure to which the vessel has been charged, while the smaller gage shows the available pressure in the supply tank. Gas flow to the vessel is controlled by a needle valve in the gage block. There is an automatic relief valve to prevent-over-charging during the filling operation.

1825A Oxygen Filling Connection with threaded connection for use with 1121/1122 Vessels
Quartz Liner for the 1108 Oxygen Vessel

For Determining Trace Elements in Combustible Samples

513A Quartz Liner

513A Quartz Liner

Trace elements in coal, oil and other combustible samples are readily determined by AA or ICP spectroscopy following combustion in an oxygen vessel. However, trace amounts of heavy metals leached from the vessel walls and electrodes during combustion can cause problems. This can be avoided by using a platinum-lined vessel, but a platinum lining is expensive. As an alternate, Parr offers a quartz liner for the 1108 Vessel that 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 Vessel with quartz liner for trace analysis by AA spectroscopy are available from Parr.

The Quartz Liner for the 1108 Vessel consists of a quartz cup, 61mm diameter x 86 mm deep, with a 514A 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 Model 1912 Quartz Liner Conversion Set.
