· Guaranteed analysis of impurities in xylene isomers
· Highest reproducibility due to revolutionary coating technique
· Temperature range 0-150oC
The CP-Xylenes column offers an ideal solution to analyzing impurity levels of meta- and para-xylene isomers. Now you can analyze low-ppm m-xylene impurities in a p-xylene product, or vice versa. The CP-Xylenes column is available in two dimensions. The 0.32mm ID provides maximum separation. Alternatively, the 0.53mm ID offers reduced analysis times by operating at high flow rates. For example, the analysis of m-xylene impurities in p-xylene is possible in less than 7 minutes. These short analysis times are essential, especially in the process industry.
