Product Analysis of Methane Photoconversion: An Online Detection Scheme | Perfectlight

1. The Challenge of Product Analysis

Methane conversion is low and product concentration small; oxygenates easily adsorb or degrade, so a slight mistake ruins accuracy. The evaluation device must pair with high-sensitivity, low-dead-volume detection.

2. Online Detection Scheme

The outlet gas of the PLR-CTPR can connect to the PLD-CGA1000 Composite Gas Analyzer for real-time quantification of multiple components, or to a Gas Chromatograph for high-resolution qualitative and quantitative analysis, shortening sampling intervals and capturing transient changes.

3. Offline Supplements

Complex oxygenates hard to resolve online can be supplemented by offline GC-MS or liquid-phase analysis, cross-validated with online data to avoid misjudging by-products.

4. Quantification Points

  • Build calibration curves with standard gases;
  • Watch the carbon balance to confirm the product carbon source;
  • Periodically calibrate the detector in long runs to prevent drift.

Frequently Asked Questions (FAQ)

Why is product analysis hard?

Low conversion, tiny product concentration, and oxygenates that adsorb or degrade mean only high-sensitivity, low-dead-volume detection gives accurate results.

What is the online scheme?

The PLR-CTPR outlet connects to the PLD-CGA1000 for multi-component real-time quantification or to a Gas Chromatograph for high-resolution analysis.

How to quantify reliably?

Use standard-gas calibration curves, monitor carbon balance to confirm carbon source, and periodically recalibrate the detector in long runs.
