Product FeaturesAgilent 7890Agas chromatographIt is a chromatograph that represents the level of new technological development and can provide excellent performance for various applications. The main reason for this is the use of electronic pneumatic control (EPC) and high-precision column box temperature control. Each EPC unit has been optimized with dedicated injection ports and detector options.

Chromatographic performance*

• Retention time reproducibility<0.008% or<0.0008 min

Peak area reproducibility<1% RSD

The temperature control of the 7890A column temperature box can meet the requirements of fast and accurate gradient temperature control. The overall thermal performance provides excellent chromatographic performance, including peak symmetry, reproducibility of retention time, and accuracy of retention index.

The combination of precise gas path pressure control and accurate temperature control can achieve excellent precision in retention time reproducibility, which is the foundation of all chromatographic detection.

Agilent's patented microplate flow path control technology has opened up a new chapter in chromatographic analysis. It is reliable, leak free, and the capillary connections inside the column can withstand long-term temperature rise and fall cycles of the GC column temperature box program.

The 7890A GC features enhanced firmware to expand the functionality of microplate flow control, as well as enhanced data system software to simplify setup and operation of blowback. These new technologies make the analysis of complex matrices and unknown substances easier, and conventional methods include two-dimensional center cutting, detector splitting, and column blowback

Analysis brings higher work efficiency and data integrity.

The 7890A GC has built-in monitoring system resources (counting, electronic recording, and diagnostics).

As is well known, Agilent GC systems have the characteristics of reliability, durability, and long lifespan. Agilent promises to guaranteeinstrumentUsing for ten years, makeinstrumentLow cost operation during use.

performance

• Supports simultaneous installation:

-Two injection ports

-Three detectors (the third detector is TCD)

-Four detector signals

The electronic circuit of the detector and the full range digital data output enable quantitative analysis of peaks across the entire concentration range (FID of 107) of the detector in a single injection.

All injection ports and detectors are fully equipped with EPC, and the control range and separation performance of special injection ports and detector components have been optimized.

Up to six EPC modules can be installed, providing EPC control for up to 16 channels.

The pressure setting value and control accuracy reach 0.001 psi, providing more accurate retention time locking for low-pressure analysis.

EPC for capillary columns has four flow control modes: constant pressure mode and gradient pressure (three-step gradient) mode, constant flow mode or gradient flow (three-step gradient) mode. Calculate the average linear flow rate of the chromatographic column.

Standardized atmospheric pressure and temperature compensation ensure that the test results remain unchanged even when there are changes in the laboratory environment.

When using instrument monitoring and intelligent diagnostic software, and even when connected to a data system, real-time monitoring of the chromatograph can be achieved through a LAN interface.

Enter maintenance and service mode with one click operation from the keyboard.

Pre programmed leak testing.

The automatic liquid sampler is fully integrated into the control of the host.

Parameters and automatic control can be set using the local keyboard or through a network data system. Clock time programming can be initialized through the front panel to initiate an event (on/off, startup method, etc.) at a future date or time.

Each deviation in analysis time is recorded to ensure that all parameters of the analysis method are archived and saved.

Various traditional gas injection and chromatographic column switching valves can be provided.

550 time events can be set.

Display all GC and automatic liquid sampler (ALS) settings on the GC instrument or data system.
