DikmaCap - Model DM-5MS / LB -Capillary Columns

DM-5MS / LB (low bleed) column is coated with a 5% diphenyl / 95% phenyl arylene dimethyl polysiloxane phase, which can inhibit the formation of ring-shaped fragments of siloxane skeleton, thereby reducing column bleed and increasing the thermal stabilty. The stationary phase has better stability; and will not exhibit oxidative degradation when there is trace oxygen in the carrier gas.
