Sample processing modules New sample prep stations from GERSTEL (Linthicum, Md.) include the QuickMix for stir- ring samples in vials from 2 to 20 mL, with an optional vial heater. The CCD cryostatic cooling station is designed to quickly cool samples and traps as low as –40 °C. Actual temperature is reported to the software for recordkeeping. A dual-camera system images barcodes on vials and plates in the SID barcode reader.


GERSTEL focused on new stations for its MPS roboticpro


workstation, such as an SPME pack-


age that includes a new injection liner which fits into the GERSTEL CIS inlet, thus avoiding septa-associated artifacts. The MPS roboticpro can also derivatize a sample on an SPME needle and is controlled with an intuitive graphical human interface.


Gas generators for GC and GC/MS GCs may require a variety of gases for the carrier gas and detectors. Quadrex Corp.’s (Bethany, Conn.) GASTRAP self-regenerating gas purifi ers for GC improve purity by a factor of 10, e.g., 15 ppm to <1 ppm (or 99.999%) (see

Figure 4). Thus, it is possible to start with lower-cost gases and upgrade them to 5 nines (99.999%) while eliminating gas line fi lters en- tirely. The purifi cation utilizes pressure swing adsorption to adsorb gases at high pressure and diff erentially release them as the pressure is reduced. Sorbents include zeolites and acti- vated carbon.


The Hydrogen and Hydrogen + Leak unit deliver fi ve nines hydrogen by removing


oxygen, nitrogen, carbon dioxide, hydrocarbons and moisture. The + Leak accessory termi- nates hydrogen fl ow exceeding 450 mL/min for 5 minutes. This also triggers an audible warning. If the fl ow is higher than 1 L/min, it is stopped immediately.


For nitrogen, the Quadrex GT-N2 and the GT- ZN2 selectively trap oxygen, water, carbon dioxide and hydrocarbons from an existing
