Great value for analytical capability
Application Area:Analysis of biological specimens for pharmaceutical residues
"Ordered through a local vendor so I do not have to contact manufacturer for after sales support, product is easy to install on GC. (I actually use Rxi-5Sil MS Columns, I don't know how to go back to change from Rxi5HT) They are low bleed and versatile for the array of compounds: pesticide and pharmaceutical residues. I have never had a bad experience with these types of columns. Great job everyone."

Very good results and effective GC columns.
Application Area:Analyze contaminants in particulate air samples
"It is easy to install and well rolled around the cage. I suggest for future design if you can put some marks on the column to follow how much length we should cut."

Good column and we continue to use it
Application Area:GC-MS pesticide analysis
"The GC-MS column from Restek is good compared to all other competitor columns. Reduces the time for backing, less bleeding at higher temperatures providing better base line and reduces silica interferences. The column life time is also pretty good compared to other columns. The ease of method development for unknown molecules is appreciable due to all the additional stability of the column."
