Restek now offers standards for natural gas and
refinery gas applications. Restek has developed
many unique columns and sampling equipment for
these industries and continues to expand product
offerings for analysts working in these fields.
These new standards are shipped in a DOT-4B-
240ET cylinder that is 3" in diameter and 9 3/8"
high. These cylinders use a CGA 170/110 connec-
tion. Restek also offers a mini-regulator specifically
made for these standards.
