The Alcott Model 719AL autosampler is a syringe style, partial or full-loop injection autosampler that accepts 8mm, 12mm or 15mm vials or microplates. Three injection volume ranges are available by choosing a 50µL, 250µL or 2mL syringe. Designed for HPLC and LC/MS applications, the 719al provides superior precision, accuracy, flexibility and reliability to your system. OPERATION Emulating a manual HPLC injection process, the 719AL has zero sample loss and can reproducibly make 1µL injections from micro inserts containing as little as 3µL of total sample. The diagram below illustrates the mechanical steps for injections with the Model 719AL.
BENEFITS - Accurate injection volumes from 0.06µL to 2mL using partial or full loop
- Internal and external needle rinse to eliminate carryover
- Optional vial trays available in three vial sizes plus microplates
- Automated dilutions, mixing, derivatizations and sample preparations
- Selectable needle depth
- Windows or EZChrom Elite 2.5 software control
- Simple to use and maintain
- System interface through RS-232, IEEE, Contact Closures and I2C
- Customized software features available
