The Teledyne Tekmar AQUATek 70 Vial Autosampler allows users to achieve the highest sample throughput on the market. Attain maximum sample capacity and throughput and improve laboratory productivity with 70 sample positions. AQUATek 70 automatically measures the sample from each vial, adds a standard solution, and then transfers it to a Purge and Trap Sample Concentrator for analysis. With AQUATek's automatic sample volume measurement and automatic standard injections, even when you walk away, you can rest assured that AQUATek 70 is performing.
With Tekmar's proprietary OptiRinse high temperature rinse system, carryover is not a concern. The unique design ensures that water, not water vapor, rinses the system and a dual chamber heating system allows the water temperature to remain high while rinsing the sample pathway efficiently, which reduces blank runs and improves your data quality. In addition, vials in the AQUATek 70 remain stationary. Because the needle moves to the vial, vial jams and drops are virtually eliminated. This method also prevents the particulate layers of ground water samples from being disturbed.
The Velocity XPT is more than a next generation Purge and Trap system, it's a revolutionary leap in technology. The XPT ensures the highest throughput with the least amount of downtime. From cutting sample cycle time nearly in half, to built-in intelligent diagnostics, Velocity XPT is the most productive Purge and Trap available today.
With the Velocity XPT, you increase the sample throughput up to 100%. This nearly double sample throughput and increases the profitability of your VOC lab without the cost of an additional GC system.
Velocity XPT Features:
- Forward Focusing Chamber:
This patent-pending technology provides the highest resolution chromatography and superior peak shape for early eluting gases. By placing an expansion chamber after the trap during the desorption modes, analytes are focused into a tight band. When analytes are tightly focused prior to desorption into the GC, dramatic improvements in chromatography resolution are evident. The FFC also efficiently desorbs which greatly reduces carryover from run to run.
- Exceptional Inertness:
Silcosteel tubing and Silcosteel-treated fittings throughout the sample pathway prevent loss of active, polar, and high-boiling compounds, and also resists corrosion.
With the simple setup and accurate control, you save time by entering all parameters electronically with Electronic Flow Control where flow and pressure parameters remain precisely the same and are constantly monitored for accurate and reproducible results.
- Automatic Leak Check, Electronic Pressure Monitor:
With intelligent diagnostics, Velocity XPT quickly and simply checks itself for leaks. If a leak is detected, system diagnostics help you isolate and pinpoint leaks. The Electronic Pressure Monitor uses a pre-set over pressure limit to identify potential pressure build ups and will shut itself down before damage can occur.
