We test our HPLC columns. Then we torture them.·· And test them again. That way, we both know the column will stay efficient. There's nothing more frustrating than having the packing settle„causing efficiency losses and poor resolution. And it happens often, particularly in reverse phase HPLC. But not with Chrompack's HPLC columns. Our quality control engineers have developed positively fiendish tortures for our columns, just to try to make the packing unstable. Only after our columns pass the second test will we deliver them to you. That includes all the HPLC columns in stock in our U.S. warehouse ready for immediate delivery to you. Naturally we include the results of the second test and test sample along with each column so you can check us, and check the installation of the column. To be sure of your HPLC results from the moment you install the column, be sure it's a Chrompack HPLC column! Call or write today for our new catalog.
