MSDS & Certificates of Analysis
We have a MSDS for all of the blends that we sell. We use the MSDS library of Airgas, the supplier of our primary 1% NIST traceable gas standards. We also generate a Certificate of Analysis for each cylinder or frequently the CofA will cover a group of cylinders.
Product Shelf Life
• Reactive gases and blends containing at least one reactive gas – 12 months or less. (See Shelf Life Chart for exceptions)
• Non-reactive gases and blends of exclusively non-reactive gases – 36 months.
• Our labels reflect the certification date of the product.

Part Numbering System
We utilize a hybrid smart number – the part number reveals important details about the product.
Format: AA-BBB-C-DDDD
1. The first two characters (AA) define the calibration gas: “01” = Ammonia
2. The next three characters (BBB) are sequential and define the concentration.
3. The next character (C) defines the balance gas: “A” = Air, “N” = Nitrogen (N2)
4. The next characters (DDDD) define the cylinder size and material of construction:
“17S” = 17 litre steel
“34S” = 34 litre steel
“34A” = 34 litre aluminium
“58A” = 58 litre aluminium
“74A” = 74 litre aluminium
“103S” = 103 litre steel
“221S” = 221 litre steel
