The Lasensor GLPC-101 Portable Compressed Gas Particle Counter is designed specifically for this type of application. It enables direct particle measurement of pressurized gases from 0.1 MPa to 1 MPa, without the need for external high-pressure separators or decompression devices.

With 0.1 μm sensitivity, eight particle-size channels, a 2.83 L/min flow rate, and integrated data management functions, GLPC-101 provides a portable solution for compressed gas cleanliness monitoring.

01 Product Overview

The GLPC-101 Portable Compressed Gas Particle Counter is designed for direct cleanliness monitoring of pressurized gases.

Unlike conventional particle measurement setups that may require pressure reduction before the gas enters the particle counter, GLPC-101 is designed to accept gas pressures from 0.1 MPa to 1 MPa directly.

The instrument can be used with CDA, nitrogen, and other inert gases, making it suitable for a variety of compressed gas monitoring applications.

With a flow rate of 2.83 L/min and particle-size channels ranging from 0.1 μm to 5.0 μm, GLPC-101 provides detailed particle concentration information across eight particle-size ranges.

Its integrated 7-inch Android display, built-in thermal printer, large data storage capacity, and RS485/Ethernet communication interfaces make it suitable for both on-site measurement and centralized data management.

02 Why Monitor Particles in Compressed Gas?

Compressed gases are often used in processes where even relatively small amounts of particulate contamination can affect production conditions.

For example, compressed air or nitrogen may come into contact with manufacturing equipment, process lines, instruments, or other critical components. If particles are present in the gas, they may be introduced into the process together with the gas flow.

Particle monitoring can therefore be used to evaluate the cleanliness of compressed gas at different points in a gas distribution system.

Typical monitoring questions include:

• Is the compressed gas clean enough for the intended process?

• Are particle levels changing at different sampling points?

• Has contamination entered the gas distribution system?

• Is the gas quality maintained after maintenance or equipment changes?

• Are filters and purification components performing as expected?

A reliable compressed gas particle counter can provide direct measurement data for these evaluations.

03 Direct Measurement Without Decompression

One of the key features of GLPC-101 is its ability to measure pressurized gas directly.

In a conventional measurement setup, high-pressure gas may need to pass through additional components before entering a particle counter. Pressure-reducing devices or high-pressure separators may be used to bring the gas to a suitable measurement condition.

GLPC-101 is designed to simplify this process.

The gas can be introduced directly into the instrument within the specified pressure range:

0.1 MPa → 1 MPa

This reduces the need for additional pressure-reduction equipment and makes on-site compressed gas testing more straightforward.

The direct measurement configuration can also reduce the number of external components required between the gas sampling point and the particle counter.

04 Technical Specifications

05 Portable Compressed Gas Monitoring

Compressed gas systems often contain multiple sampling points distributed across production areas and equipment.

A portable particle counter allows users to move between different sampling locations and perform measurements where needed.

GLPC-101 combines the particle detection system, display, data storage, printing, and communication functions in a single instrument.

This makes it suitable for applications where compressed gas cleanliness needs to be checked at different locations rather than monitored from one fixed installation point.

Typical measurement locations may include:

Gas Supply → Distribution System → Point of Use → Process Equipment

By comparing measurements from different points, users can obtain additional information about particle levels throughout the compressed gas system.

06 Application Areas

Semiconductor and Electronics Manufacturing

Compressed air and nitrogen are commonly used in semiconductor and electronics manufacturing processes.

GLPC-101 can be used to monitor particulate contamination in compressed gas systems and provide particle concentration data for process quality control.

Pharmaceutical Manufacturing

Compressed gases may be used in pharmaceutical production and supporting processes.

GLPC-101 can be used to evaluate particle cleanliness at selected gas sampling points and support environmental and process monitoring activities.

Precision Manufacturing

For precision manufacturing processes where compressed gases are used around sensitive equipment or components, particle monitoring can help assess gas cleanliness.

Compressed Air Systems

GLPC-101 can be used to monitor particle levels in Clean Dry Air and other compressed gas systems, including measurements at different points within a gas distribution network.

Nitrogen Gas Systems

The instrument can also be used for nitrogen particle monitoring where gas cleanliness is an important part of process control.

07 Compressed Gas Particle Monitoring Workflow

A typical compressed gas particle monitoring process can be organized as follows:

Select Sampling Point

↓

Connect GLPC-101 to the Compressed Gas Source

↓

Set Measurement Parameters

↓

Directly Introduce Pressurized Gas

↓

Detect and Classify Particles

↓

View Particle Concentration Data

↓

Store / Print / Export Measurement Records

This workflow allows operators to perform compressed gas cleanliness measurements directly at the sampling location.

08 Data Management and Communication

Particle monitoring is not only about obtaining a measurement value. In production environments, measurement records may also need to be stored, reviewed, exported, or transferred to a centralized management system.

GLPC-101 provides multiple options for measurement data management.

The instrument can store more than 500,000 measurement records, including:

• Measurement date

• Measurement time

• Particle counts for each size channel

Data can be exported through a USB flash drive.

For system integration, GLPC-101 provides RS485 and Ethernet communication interfaces and can connect with a host system through its communication protocol.

This allows measurement data to be incorporated into broader data management, reporting, and alerting workflows.

09 A Portable Solution for Pressurized Gas Cleanliness Monitoring

Particle contamination in compressed gas cannot always be evaluated using the same approach as ambient air particle monitoring. The pressure of the gas itself creates additional requirements for the measurement system.

GLPC-101 is designed specifically for this application, allowing users to measure compressed gas directly within a pressure range of 0.1–1 MPa.

With 0.1 μm particle detection, eight particle-size channels, integrated data storage, on-site printing, and RS485/Ethernet communication, GLPC-101 combines particle measurement and data management functions in a portable instrument.

For semiconductor, pharmaceutical, precision manufacturing, and other industries where compressed gas cleanliness is important, GLPC-101 provides a practical solution for on-site particle monitoring.
