OI Analytical LV-20 Standards Addition Module
The LV-20 Standards Addition Module is an option for the 4551A Purge-and-Trap Autosampler that injects programmed volumes (1, 2, 5, 10, or 20 microliters) of internal standard, surrogate or matrix spike standards to improve the accuracy and precision of GC-GC-MS analyses.

- Các thông số kỹ thuật
The LV-20 is equipped with high-speed injection valves that minimize standard usage and decrease laboratory operating costs for expensive standards. The high-speed injection valves inject user programmed volumes of standard with no excess overfill volume that fixed-loop based systems require to operate.
All LV-20 functions are programmed using the touchscreen and Windows® CE software on the Eclipse 4660 purge-and-trap sample concentrator.
- Automatically adds internal standards, surrogate or matrix spike standards at operator-defined intervals
- Significantly reduces the volume of standards used in GC-MS analysis
- Amber glass reservoirs protect standards from UV light degradation
- Mounts directly on top of a 4551A autosampler
- Dry erase panel for noting standards in use on the instrument
