RADNOR, Pa. -- March 13, 2013

Airgas, Inc. (NYSE: ARG), one of the largest U.S. suppliers of specialty gases
and equipment, will unveil three new products designed to maximize efficiency
and purity in gas chromatography at the Pittsburgh Conference on Analytical
Chemistry and Applied Spectroscopy (PITTCON) in Philadelphia, March 18^th –
21^st. Two of the products — Airgas Gas Flow Calculator and Airgas SmartTag —
have recently garnered the Golden Gas Award™ from Gases & Instrumentation
International magazine. The Airgas Ultra High Purity Regulator will also be
added to Airgas’ diverse range of gas equipment solutions and will be on
display at PITTCON.

“Our customers are always striving to streamline their gas usage and find
efficiencies where possible, and that’s particularly true during the current
helium shortage,” explains Bill Russo, Vice President – Airgas Specialty
Gases. “Our newest system components and software which will be on display at
PITTCON support laboratory gas users in their efforts to get the most out of
their gas purchases.”

The award-winning Airgas Gas Flow Calculator helps laboratories evaluate total
gas usage for all gas chromatography applications and achieve gas reduction
goals. It can be used to calculate actual gas usage at each instrument
attached to the gas stream to determine amounts of waste from gas leaks or gas
being used for non-analytical applications. The Airgas Gas Flow Calculator can
also help determine if switching from helium to hydrogen as a carrier gas will
be a cost-effective solution.

“We’ve found that there is often miscommunication between chemists and gas
supply representatives because they speak in different gas measurements —
chemists reference linear gas rates and columns, where as gas representatives
speak in cubic feet and cylinders,” says Frank Kandl, Product Manager – Airgas
Specialty Gas Equipment. “With the help of the Airgas Gas Flow Calculator,
both parties are on the same page and the accurate amount of gas needed may be
provided more effectively.”

Also to be unveiled is the Airgas SmartTag, the industry’s first visual alert
system for managing gas expiration, as well as on-site verification of gas
contents, Certificate of Analysis, point-in-time validation of devices
connected to the cylinder, cylinder fill history, location where the cylinder
was filled, and more. The unique microprocessor collar fitted to each cylinder
provides instant data retrieved by handheld and wall readers so that
information may be printed or blue-toothed to a customer’s own data base.
Unlike common Radio Frequency Identification (RFID) devices that contain
minimal data, the award-winning Airgas SmartTag collars store up to 21 fields
of data for optimal cylinder gas storage, inventory, and reorder processes.

“The capabilities of the data provided by the collars are limited only by how
a customer would like to use it. It could be as simple as a quick visual
indication that the cylinder is ‘in date’ or an extensive report for all
cylinders on site,” explains Kandl.

The latest specialty gas regulator offering from Airgas is the Ultra High
Purity Stainless Steel Regulator, designed to drastically reduce the gas path
and prevent contaminants from entering the gas stream during cylinder
change-outs. The new regulators are designed with a check valve cylinder
connection, packless diaphragm valve built into the regulator body, and 1/8”
stainless steel compression fitting to maintain gas purity. As the only
regulator with a diaphragm valve built into the body, the Airgas Ultra High
Purity Stainless Steel Regulator has less internal volume which produces
better sensitivity and responsiveness.

“This regulator series has unique features that make it an excellent choice
for high-tolerance gas mixtures and use in high purity applications,” explains
Kandl.

More information on the new Airgas products, as well as information on all
Airgas specialty gas product and service offerings, is available at the Airgas
exhibit (Booth #1219), March 18^th – 21^st. Registered PITTCON attendees who
visit the Airgas exhibit will be entered in a drawing for a grand prize of a
Microsoft Surface™ tablet. For more information on PITTCON, visit
