Scheduled maintenance of NeoCHROM chromatographs

Neochrom Asia provides scheduled maintenance for NeoCHROM chromatographs in Kazakhstan. We inspect the instrument and auxiliary equipment, service sample introduction and detection assemblies, and replace consumables according to the work scope. Regular maintenance helps identify contamination, leaks and wear in time, maintain stable chromatograph operation and plan laboratory costs.

Maintenance tailored to your instrument

Below is an example of maintenance for a gas chromatograph NeoCHROM Class B. We determine your instrument's work scope by its configuration, operating conditions and assembly condition. Required consumables and cost are clarified before servicing begins.

Power supply system

• Inspection of power supply and distribution lines for damage.
• Elimination of detected damage to lines within the agreed scope of maintenance.
• Checking the uninterruptible power supply.

Gas supply and gas distribution

We check the condition of gas lines and auxiliary equipment that ensures the operation of the chromatograph.

• Inspection of gas distribution lines, detection and elimination of damage within the agreed scope of maintenance.
• Search for sources of gas leaks and elimination of detected leaks.
• Checking the hydrogen generator and compressor, if they are part of the complex.

Registration and data processing

• Overview of data exchange lines between the device and the workstation.
• Checking the workstation.
• Verification of software for management, registration and data processing.

Autosampler and sample introduction

We service the automatic sample introduction system and check the condition of its consumables.

• Checking the operating parameters of the autosampler.
• Inspection of electromechanical units of the autosampler and their cleaning if necessary.
• Checking the condition of the syringe, cleaning it or replacing it if necessary.
• Checking the wash and drain vials, cleaning or replacing them as needed.

Injector and carrier gas lines

• We inspect the liner, glass wool and septum. Replacement follows the work scope for the specific injector.
• Leak testing of carrier gas, septum purge and split vent lines.
• Elimination of detected leaks.
• Checking the filters of the relevant gas lines and replacing them if necessary.
• Checking gas and temperature regimes of the injector.

Column oven and chromatographic column

• Checking the temperature regimes of the column thermostat.
• Checking the state of the capillary chromatographic column.

Detector

The list of works depends on the type of installed detector. For a flame ionization detector, maintenance includes:

• Inspection and cleaning of the jet, collector and ignition components.
• Checking the operating parameters of the supply of hydrogen, air and additional gas.
• Checking the temperature regimes and metrological characteristics of the detector.

Conditioning

The complex of works includes conditioning of the injection port, capillary column and detector. The modes are selected taking into account the installed column and the configuration of the device.

Maintenance planning and warranty service

Include annual maintenance in the laboratory work schedule and budget. When preparing for service, we check the warranty terms in your instrument documents and account for required service intervals.

Full terms are provided on the Warranty and service page.

Plan maintenance for your chromatograph

Provide the instrument model, serial number, configuration and last maintenance date. Tell us when maintenance would suit your laboratory. We will use these details to prepare the work scope, consumables list and cost estimate.
