An Independent Commercial Laboratory

What Do We Offer?

We understand what your requirements are for selecting an independent commercial laboratory; namely, an experienced staff and helpful service — at a fair price. By respecting these basic needs, Atlantic Analytical has for many years provided expert, trustworthy information to hundreds of clients ranging from Fortune 500 firms to small businesses.

Air Separation Unit (ASU) Gases

LiN, LOx, & LAr

The most commonly used “bulk” gases – nitrogen, oxygen, and argon – are all generated by distillation of air, which is composed of approximately 78% nitrogen, 21% oxygen, and 0.9% argon. The individual gases are isolated by weight as they move through an air separation unit (ASU) distillation tower, and after further purification the separated gases are cooled and compressed into liquid (cryogenic) form for storage and distribution using bulk tanks, rail cars, and trailers.

These bulk gases undergo detailed analytical testing to ensure they have been adequately separated from each other and that all atmospheric contaminants have been removed from the final product. Atlantic Analytical Laboratory has been performing ASU gas quality analysis for major gas suppliers for over 20 years.

AAL Goes Above & Beyond

High Purity Gas Analysis

Pure gases such as Nitrogen, Oxygen, Argon, Hydrogen, Helium, and Carbon Dioxide are typically available in a wide range of purity grades (zero grade, UHP grade, scientific grade, etc). The proper grade of gas to use for a given application is often established by guidelines or regulations published by agencies such as USP/NF, EP, CGA, EIGA, NFPA, MIL-SPC, or as outlined by internal customer specifications.

Typically, when an end user suspects contamination problems with a pure gas supply, they will not trust the original supplier to verify their own product gases and look to an independent, certified, third-party laboratory for help. Atlantic Analytical Laboratory has performed high purity gas analysis for customers of every major gas manufacturer at some point during our 30-year history, usually at the request of the original supplier as they are familiar with our extensive analytical capabilities and long history of reliable analytical work.

AAL has the capability to match high-purity gas certifications for all commonly used gases, often going beyond the original manufacturer’s specifications for both impurity compounds analyzed and quantitation limits.

Gas Mixture Analysis

Isotopic Abundancy Analysis

Many commercial and industrial processes rely heavily on custom-made gas mixtures, ranging from shielding gas mixtures used in welding to isotopic gas mixtures used for medical imaging and beyond. If there is a question as to the accuracy of a blend received from your supplier, Atlantic Analytical Laboratory can easily verify gas mixtures using a variety of analytical methods. This includes specialty isotopic mixtures, where we can use Mass Spectrometry and/or GC/MS to determine the ratio of the varying isotopes present in a gas mixture with part-per-million level accuracy.

Compressed Air / SCBA / SCUBA

A simple, convenient program

Compressed air has many applications, including use in Self-Contained Breathing Apparatus (SCBA) and Self-Contained Underwater Breathing Apparatus (SCUBA). Atlantic Analytical Laboratory has a simple, convenient program established to guarantee SCBA / SCUBA Breathing Air Quality as described in:

The Gold Standard for Gas Analysis

Sample Submissions

The most critical step in any analytical program is initial sample collection – great care must be taken to ensure the sample collected is truly representative of the source. AAL has a large selection of sampling cylinders and other sampling equipment available for all types of gas and liquefied gas sampling. If you are uncomfortable collecting samples or just want to make sure everything goes smoothly, we can send one of our experienced personnel directly to your facility to collect samples on site for you. We look forward to working with you soon!
