We have heard customers recommend hot aqua-regia, cold aqua-regia, baking or other cleaning regimens. In general, however, Precision Glassblowing recommends that torches not be cleaned. As odd as it may seem, the constant strain of temperature changes and solvents used for cleaning actually shorten the life-span of a torch. There are, of course, exceptions. For more information, talk to your sales representative.
The A-type nebulizer was the original concentric nebulizer developed, and has an internal capillary ground flush to the nose. The technology has since evolved into a C-type neb. which has an internal capillary slightly recessed with regard to the nose resulting in a higher tolerance for dissolved solids and a more consistent aerosol making it much preferred over the older A-Type. Sometime after this, there was a push to consume less argon and so the K-type neb. was developed which functions much like a C-type but uses only 0.7 liter/minute of argon as opposed to the 1 liter/minute of argon the C-types use.
Simply put, an axial torch is one used in an instrument arranged in an axial, or horizontal, orientation. A radial torch is used in a vertical orientation.
Precision Glassblowing strives to maintain stock on all common ICP and ICP/MS consumables. Custom and back ordered items usually carry a 2-4 week turn-around-time assuming raw materials are in stock. On occasion, the availability of raw materials may require longer lead times.
Order expediting is available in most cases for an additional fee. Please contact your sales representative for more details.
