Which is a good imported second-hand gas chromatograph

The physical specification parameters of Shimadzu GC-14B gas chromatograph sorted according to search results are as follows:

Host body parameters

Project specification source

Weight approximately 40 kg

The size is not clearly stated, but the base accessory (P/N 221-44388-91) is compatible with the standard experimental bench

Installation extension requirements

Space layout

Reserve side and rear heat dissipation space (effective heat dissipation is required for high-temperature components during operation);

Additional space is required when paired with an automatic headspace system (AHS) or a purge capture system.

Accessory impact

Installing split/non split injection ports (SPL-14) or large-diameter capillary column connectors (WBC) may increase the front end width;

TCD detector components require separate connectors and graphite seals.

Typical configuration size reference

Type of injection port: Fill column injection port depth of about 200 mm (including glass liner and connector);

Detector unit: FID detector with a height of approximately 150mm (including nozzle and collection electrode);

Whole machine footprint: Conventional configurations require a laboratory bench area of ≥ 0.8 m ² (including gas pipelines and workstations).

Note: The specific dimensions may vary greatly due to the selection of modules (such as automatic sampler and multi detector), and it is recommended to follow the actual configuration plan.

The following is a comprehensive summary of the core specification parameters of Shimadzu GC-14B gas chromatograph:

Core performance parameters

Parameter specifications

The detection system supports dual hydrogen flame ionization detector (FID) and dual thermal conductivity detector (TCD)

Injection system - packed column or capillary injection system

-Support diversion/non diversion function

Temperature range column temperature box: room temperature+10 ℃~420 ℃ (low-temperature accessories can be extended to -90 ℃)

Program heating with 20 stages (including cooling program)

Hardware configuration

Detector unit

FID detector: quartz nozzle (diameter 1.2mm) and dedicated collection electrode component

TCD detector: requires independent configuration of graphite seals and connectors

Injection port expansion

Can install split/non split injection port (SPL-14), compatible with glass liner (2.6mm/3.2mm)

Support large-diameter capillary column connectors (WBC accessories)

Pneumatic system

Standard molecular sieve filter (molecular sieve model 201-36992-91)

The carrier gas pipeline is compatible with 1/8 inch, 3/16 inch, and 1/4 inch stainless steel chromatography columns

Physical parameters

Component specifications

The weight of the host is about 40 kg

Column temperature box with a capacity of 231 mm in length, 361 mm in height, and 163 mm in width

The standard configuration for the whole machine requires a test bench area of ≥ 0.8 m ² (including gas pipelines)

Key features and extensions

Workstation compatibility

Standard Chinese version chromatography workstation, supporting multi-channel data acquisition;

Security maintenance

High temperature components (such as injection ports and detectors) require specialized tools for disassembly, and nozzle replacement must match the diameter specifications;

Power configuration

Host power supply: 220V (part number 221-44403-92);

The injection port module requires independent power supply (capillary injection port accessory number 221-32547-93).

Note: The specific configuration may vary due to differences in second-hand equipment or selected accessories. It is recommended to verify the technical drawings and compatibility of accessories through the supplier.
