Zebron GC Columns by Phenomenex Inc

"The Zebron ZB-1 capillary GC columns have demonstrated to us that they provide good value for money. The reactants we use in our manufacturing process have in the past reacted with the column chemistry, destroying the usefulness of the column. We have found the Phenomenex brand to be very robust and more resistant to loss of theoretical plates than other similar column brands"

"ZB-624 column is ideal for GC and GC-MS. Very low bleed and ideal for using in GC-MS for volatile solvents"

"Most of the time we use Phenomenex columns which are easy to use and long lasting with less cost"

"I've been working with this company for many years. They have never failed to supply us with the methods and the equipment necessary to help us solve our problems. I would highly recommend this company to all. They always supply us with the information required to make a purchase."

"The column is user friendly and is easy to use. It makes my life easier in the lab with my work load. Easy to use and a good value price/utility."

"We got a much better reproducibility in the separation of aqueous samples compared to the classic WAX column. Also at the level of stability and selectivity there have been considerable improvements. I definitely recommend it for aqueous samples and acidic compounds separations."

"I analyze C14 (tetradecanol) and C16 (esadecanol) by GC (Agilent 6890) using ZB-1. After each run with Restek RTX-1, I had to clean the injector and replace the gold seal and inlet line. After most runs with ZB-1, I could get away with just changing the inlet and not having to clean or trim the column. The separation was similar but the Zebron lasted about 2 to 3 times longer, which means saving money."
