Gas quality & purity

Continuous monitoring with TDLAS-based systems to ensure clean, stable, and contamination-free process gas.

Overview

Many industrial processes rely on high-purity gas, whether it’s CO₂ for urea production, NH₃ in fertilizer lines, CH₄ in upgrading systems, or specialty gases in semiconductor manufacturing.

Even small deviations in gas quality can cause process instability, off-spec product, equipment damage, or regulatory non-compliance.

Continuous, real-time measurement ensures the gas entering or circulating through the system meets strict purity requirements at all times. Typical purity-limiting contaminants include: NH₃, CO₂, H₂O (moisture), H₂S, O₂, Acid gases (HCl, HF). Beamonics’ TDLAS analyzers detect these contaminants with high accuracy and zero drift.

Why gas purity matters

  • Process Stability: Contaminants change reaction kinetics, damage catalysts, or cause inconsistent production quality.
  • Equipment Protection: Acid gases and moisture cause corrosion, fouling, or membrane degradation.
  • Product Quality Assurance: Industries like fertilizer, semiconductors, and food/pharma require tight purity control to maintain yield and consistency.
  • Regulatory & Safety Requirements: Off-spec gas can create unsafe operating conditions or violate compliance requirements.
  • Cost Control: Uncontrolled contamination leads to wasted chemicals, downtime, and premature equipment replacement.

How we ensures gas quality

Beamonics analyzers provide:

  • Continuous, real-time purity measurement

  • Sub-ppm detection for NH₃, H₂O, H₂S, O₂, CO₂

  • No calibration drift

  • Stable performance in corrosive or humid gas streams

  • Fast response for immediate corrective action

Whether installed in-situ or extractive, the system verifies purity before gas reaches critical equipment or process stages.

How our technology works

1. Laser Emission

A tunable diode laser emits specific colors (wavelengths) of light that is directed through the gas sample.

2. Absorption Measurement

As the laser passes through the gas, molecules absorb some light, which is then measured and recorded.

3. Concentration Calculation

The absorption is analyzed to determine the gas concentration, providing precise, real-time measurements.

Frequently asked questions

What problems do your gas analyzers solve?

We help process and environmental teams measure critical gases in real time (e.g., CH₄, CO₂, H₂S, HF, HCl, H₂O, O₂) for safety, quality, and compliance across biogas, CCUS, battery, chemicals, and more.

How is TDLAS different from NDIR or electrochemical sensors?

TDLAS measures the unique absorption line of a gas with a laser. It’s fast, selective, stable, and needs less frequent calibration than NDIR/electrochemical cells in most tough processes.

Do you offer both in-situ and extractive measurement?

Yes. We provide line-of-sight in-situ probes for hot/wet ducts and extractive analyzers for conditioned sample lines. We help you choose based on dust load, pressure, temperature, and access.

What gases do you measure today?

Common: CH₄, CO₂, H₂S, NH₃, HF, HCl, H₂O, O₂, CO, and others on request. Please ask if your target gas isn’t listed.

How fast is the response time?

In practice, there is no T90, as our TDLAS analyzers operate in real time. For example, we deploy solutions in high-speed processes with several 100 Hz/ms. However, typical end-user requirements are often 1–2 seconds in situ and 2–5 seconds for extractive applications (application-dependent).

What accuracy and detection limits can we expect?

Process-ready accuracy (often ±1–2% of reading) and low ppm detection for many species. We’ll quote measurement range, repeatability, and LOD per application.

What does maintenance look like?

Maintenance is typically minimal. Mainly optics checks and purge air filter changes. No consumable cells. Annual verification is standard. No calibration is needed, since TDLAS is self-referencing. 

Can you integrate with our DCS/PLC/PC?

Yes, please review the specific datasheet for the product you are interested in. Standard configurations are RS-485, RS-422, USB, 4-20 mA, and so on. Our solution comes complete with a servicing and commissioning software and integration-ready API. We are happy to help if you are unsure which integration method is best for you. 

What certifications and ATEX/IECEx options are available?

We offer some enclosures and probes for industrial and explosive areas. Please reach out to us if you have questions regarding ATEX/IECEx, and we will do our best to assist you. We are committed to quality and are certified to ISO 9001:2015.

What are typical lead times and pricing models?

Most systems ship in 4–6 weeks, while some custom builds can take up to 12 weeks. Pricing depends on gas set, configuration, and explosive-area needs. We also offer pilot programs.
