Sample Tray (not shown): A 51 position, all aluminum, sample tray is provided
to hold sample vials. The tray is removable, and when installed, rests on top of
the aluminum tray cooler for cooling the samples.
1. Robotic Arm: The robotic arm is used to move the sample vials. A vial
gripper is used to remove the vials from the tray and place them in the
appropriate sampling positions.
2. Water Probe: The water probe is a patented concentric needle to puncture
water vials, pressurize, and displace water samples to the syringe. After
sampling, the probe is rinsed in a chamber that prevents sample from
spraying onto the instrument components.
3. Soil Probe: The patented soil probe and the Needle Sparge probes
incorporate a "T" fitting design for attachment of water and heated transfer
line. The probe is installed in a heated oven and easily removable for
cleaning or replacement.
4. 26 mL Syringe: A 26 mL syringe is used to move sample, blank, flush and
waste water. The syringe is mounted upright, directly into the valve manifold.

5. Standard Valve: The standard injection station uses a 6 port valve with a 1
µL internal loop. The internal standard groove is filled by pressurizing the
standard reservoir and rotating the valve to positions 1 & 2, (Std. 1, Std.
2).Water samples or dilution water passes through the loop to deliver the
