J2-Scientific - Version AccuPrep -PC Control Software

Method Programming:

• Five programmable discard or collect fraction.
• Each collect fraction can be split into multiple fractions.
• Automatic pump equilibration time programmable for each method.
• Programmable precise rinse volume after sample injection and sample collection.

Sequence Programming:

• Tabular spreadsheet for quick sequence programming.
• Program multiple columns and pressure ranges in the same sequence.
• Add/Remove/Insert samples during sequence processing.
• Store detector plot for each sample.
• Copy, Cut and Paste functions.

Injection: 

• Programmable injection volume from 1µL to 15mL.
• Sample does not enter syringe during aspiration.
• Multiple injections from the same sample.

Detector Control:

• Automated control of detector and chromatography software: generates unattended event mark/start pulse.
• Automatic zero/null before sample injection.
• Data collection from two detector inputs simultaneously.
• View detector data during sequence processing.
• Three selectable detector input ranges.

Pump Control:

• Flow rate ramping from .01 - 2 mL/sec.
• Automatic flow-rate calibration.
• Programmable over-pressure limits up to 2500 psig.
• Programmable under-pressue limit to detect loss of solvent flow.

Probe Tracking:

• Sample probe tracks down with top of sample during sample pick-up to minimize probe contact and rinsing requirements.

Solvent Watchdog:

• Keeps track of mobile phase level and warns when low; programmable warning thresholds.
• Will pause sequence until solvent is added to avoid sample loss.
• Enter mobile phase description and lot numbers for reports.
