Isobutylene Calibration Gas

Isobutylene calibraton gas available now!

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.

Part Numbering System
We utilise a hybrid smart number – the part number reveals important details about the product.
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:
o “103S” = 103 litre steel
