DikmaCap GC Column DM-5MS / LB, 30 m x 0.25 mm x 0.1 μm, PN: 8719
• Cross-linked 5% diphenyl / 95% phenyl arylene dimethyl polysiloxane
• Very low bleed
• Improves the resolution between Benzo[b]fluoranthene and Benzo[k]fluoranthene
• Similar to DB-5MS
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.
DM-5MS / LB column is similar to DM-5MS. The DM-5MS / LB has good sensitivity and peak symmetry for strong polar and basic compounds. We recommend DM-5MS / LB column for analysis of semi-volatile compounds such as PAHs and PCBs.
