Last drop filters
Supplier: Restek
The flat filter element sits parallel to the bottom of the mobile phase reservoir, allowing the filter to draw 98% of the mobile phase without drawing air into the system. Conventional cylindrical mobile phase filters begin to draw air into the system when approximately 10% of the solvent remains in the reservoir.

Capillary columns, Rtx®-200MS (fused silica)
Supplier: Restek
Rtx-200 columns have accomplished many difficult separations. The trifluoropropylmethyl polysiloxane stationary phase has a unique selectivity that changes elution orders and resolves compounds that phenyl, cyano, or carbowax phases can not. These columns offer exceptional thermal stability, low bleed, and superior inertness - even for active compounds such as phenols, and with sensitive detectors such as ECDs, NPDs, and MSDs.
