II. CONNECTING THE COLUMN TO THE HPLC INSTRUMENT
Handle the column with care. Do not drop or hit column on a hard surface
as it may disturb the bed and affect its performance.
1. Correct connection of 1/16 inch outer diameter stainless steel tubing
leading to and from the column is essential for high-quality chromato-
graphic results.
9. Benzo(a)anthracene - 2 ppm
10. Chrysene - 2 ppm
11. Benzo(b)fluoranthene - 4 ppm
12. Benzo(k)fluoranthene - 2 ppm
13. Benzo(a)pyrene - 2 ppm
14. Dibenzo(a,h)anthracene - 4 ppm
15. Benzo(g,h,I)perylene - 4 ppm
16. Indeno(1,2,3-cd)pyrene - 2 ppm
10. Pyrene - 2 ppm
11. Benzo(a)anthracene - 2 ppm
12. Chrysene - 4 ppm
13. Benzo(b)fluoranthene - 4 ppm
14. Benzo(k)fluoranthene - 2 ppm
15. Benzo(a)pyrene - 2 ppm
16. Dibenzo(a,h)anthracene - 4 ppm
17. Benzo(g,h,I)perylene - 4 ppm
18. Indeno(1,2,3-cd)pyrene - 2 ppm
2. When using standard stainless steel compression screw fittings, it is
important to ensure proper fit of the 1/16 inch outer diameter stainless
steel tubing. When tightening or loosening the compression screw, place
the 5/16 inch wrench on the compression screw and the other 3/8 inch
wrench on the hex head of the column endfitting. Note: If one of the
wrenches is placed on the column flat during this process, the endfitting
will be loosened and leak.
