GC Columns

Varian's Quality Assurance

Varian GC columns are produced following ISO 9001 certified procedures. This process guarantees you that all Varian GC columns are produced using a systematic and controlled process. Besides the drawing of the fused silica tubing, Varian also synthesizes the stationary phases that are used for capillary column preparation. The inertness, neutrality, reactivity, polarity and temperature stability are directly dependent on the purity of the stationary phase used. By making the phase ourselves we are able to produce capillary columns with the tightest specifications. To prove it the specifications for column bleed, the retention index, asymmetry and plates per number are published.

Bleed
Column bleed is measured in pA (pico Amperes) at the maximum operating temperature with a calibrated FID. The FactorFour program has guaranteed the lowest bleed specifications, up to a factor four better as other competing columns. Low bleed is an indicator of superior column stability and longer life-time with increased analytical sensitivity, accuracy and precision.

N/m
The numbers of plates per meter (N/m), is an indication of the efficiency of a column, a measurement of column separation power.
back


Asymmetry
The peak asymmetry factor (As) indicates the quality of column inertness and deactivation. Low asymmetry values means a better peak-shape providing optimal column resolution, lower detection limits and analytical accuracy.
