Nexis GC-2030

Gas Chromatography

Various Advanced Functions Improve Energy Efficiency

Maximized Column Oven Functionality

- Column Temperature Control Function -


Column Cooling Rate Selection

Cooling the column oven too quickly could damage the liquid stationary phase in columns. Therefore, the cooling rate on the Nexis GC-2030 can be easily set to three different levels of high, medium and low, to minimize damage to column liquid phases and maximize the column's life time.


Improved Temperature Setting Freedom

Due to the improved temperature control accuracy, the GC oven temperature can be controlled from two degrees above room temperature. That means temperature can be controlled accurately even at temperatures close to room temperature.

Graphical Display of Temperature Program

Temperature programs can be freely edited via the touch panel on the GC unit. Created temperature programs can be displayed in combination with chromatograms.

Minimized Running Costs
- Automatic Start and Stop Functions -

The automatic start and automatic stop functions reduce running costs. The automatic stop function can save electricity by automatically stopping GC temperature control when analysis is completed. Later, after a specified time has elapsed, it also stops carrier gas and detector gas control. The automatic start function starts gas control after a specified period of time and then starts temperature control.

Minimized Helium Gas Consumption
- Carrier Gas Saver Function -

Lowering the split ratio during analysis using split/splitless sample injection decreases the carrier gas consumption by reducing the amount of carrier gas discharged outside from the split flow channel.

In this example, carrier gas is saved by setting the split flowrate to 200 mL/min only during sample injection and then reducing it to 20 mL/min at all other times. Furthermore, after batch analysis stops, the saver function keeps saving carrier gas while it waits for the next batch analysis to start.


Analysis time: 30 min. Split ratio: 100
Carrier gas saver function: Split ratio set to "10" one minute later
Column temperature: 170°C
Column: 0.25 mm I.D., 30 m long, 0.25 μm film thickness

Diagnoses Instrument Operating Status
- Self-Diagnostic Function -

Self-Diagnostic Function

Self-Diagnostic Function

The instrument operating status can be confirmed using the self-diagnostic function (system check). The status can be checked in detail to determine the septum/insert usage status, presence of active temperature sensor errors, gas supply pressure, status of each gas control function, ignition activity status, direct current voltage, and to confirm that the Analog / Digital converter or other functions are functioning properly. Periodically diagnosing the instrument status can help prevent unexpected downtime.

Automatic Notification of Replacement Timing
- Monitoring Function -

Analysis Counter Screen

Analysis Counter Screen

The Nexis GC-2030 includes various monitoring functions. These functions remind users when to replace consumables and help ensure data quality. Power consumption can also be monitored in real time.

  • Syringe usage counter
  • Refrigerant consumption monitor
  • Septum usage counter
  • Power consumption monitor
  • Insert usage counter
