≤1 Pg Portable Gas Chromatograph Laboratory GC Instrument for Transformer Oil Analysis

Why are some chromatograms "inaccurate" or "unable to produce peaks"?

Most of these problems stem from three sources: unstable air path control, large temperature fluctuations, and mismatched parameter settings

We have made several practical changes to address these issues:

• Air system upgrade

  Replace traditional mechanical valves with high-precision proportional valves and pressure/flow sensors. The pressure resolution is 0.01Psi, and the flow resolution is 0.01mL/min. This is not propaganda, the actual control is more stable, especially suitable for long-term series sampling.

• Column box dual software protection

  Not only does it have a temperature control accuracy of ± 0.1 ℃, but it also has dual software protection to prevent the loss of stationary phase or sample decomposition caused by temperature loss control.

• Network architecture avoids human errors

  Three IP independent design, not a gimmick. In actual testing, many "inaccurate" results are actually due to human error in parameter modification. This architecture allows different roles to only view the data they should be viewing, reducing the risk of misoperation.

• Workstation comes with baseline deduction and peak intelligent recognition

  In practical use, baseline drift during program heating can be automatically deducted, reducing manual intervention.

These changes will not allow you to peak 100% every time, but they can reduce the probability of "inexplicable uncertainty".

Product Advantages

1. Remote diagnosis and update: supports remote viewing by manufacturers - requires user authorization, does not visit randomly

2. Multi role permissions: Quality inspection, production, and management can view separately to avoid mistakenly changing parameters

3. Offline processing does not occupy equipment: automatic analysis after sampling is completed, without affecting the next injection of the sample

4. Flexible file naming: can be named according to date, number, and automatic injection frequency, making it easy to find data in the later stage

5. Compatible with CDF files: can interface with data exported from workstations such as Agilent

Application Scenarios

	Monitoring of intermediate content in chemical plants
	The workshop needs to measure the target component content in the reaction solution every 2 hours. Connect this device to an automatic sampler, set up batch processing, and automatically inject, analyze, and save samples at night. The results can be viewed directly the next day.

	Analysis of Natural Gas Calorific Value
	It is necessary to analyze both C1 and C6+hydrocarbons simultaneously CO2,N2. Using a TCD+FID dual detector in series, all components are extracted in one injection, and the workstation automatically calculates the calorific value.
