EXPEC 3100 Portable Volatile Organic Compound (VOC) Analyzer

Product Introduction
The EXPEC 3100 Portable VOC Analyzer is designed for rapid field screening, detection, and source identification of volatile organic compounds (VOCs). It uses a flame ionization detector (FID) for total hydrocarbon measurement and offers an optional photoionization detector (PID) for detecting a broad range of VOCs and certain common inorganic compounds.
With a compact 3.7 kg main unit, response times under 3.5 seconds, and an explosion-protected design, the EXPEC 3100 supports industrial inspections and environmental fieldwork. Typical applications include VOC source tracing, emergency pollution investigations, fugitive emission surveys, and leak detection and repair (LDAR) inspections at chemical facilities.
The optional EXPEC 3100I handheld controller works wirelessly with the analyzer to control measurements, record inspection-point data, retrieve location information, and upload records to a cloud platform. Its barcode or QR-code scanning and image-based inspection-point information help streamline field surveys and LDAR documentation.

Performance Features
• Optional FID and PID detectors: Supports total hydrocarbon measurement and broad VOC screening, depending on detector configuration.
• Rapid response: The specified time to reach 90% of the final reading is less than 3.5 seconds under the stated test conditions.
• Wide measurement ranges: FID range of 1–50,000 ppm methane and PID range of 0.5–2,000 ppm isobutylene.
• Explosion-protected design: Specified protection marking is Ex d ia IIC T4 Gb for use in applicable hazardous gas environments, subject to site and certification requirements.
• Lightweight and portable: The main analyzer weighs approximately 3.7 kg for convenient field transport.
• Wireless handheld control: The optional EXPEC 3100I communicates with the analyzer through an industrial Wi-Fi connection.
• Cloud-based LDAR workflow: Supports one-touch data upload and inspection-point records for networked applications.
• Open communication protocol: Designed to support compatibility with mainstream LDAR data analysis platforms.
• Extended operating time: Both the hydrogen supply and rechargeable battery are specified to support more than 10 hours of continuous operation under stated conditions.
• Convenient hydrogen handling: The dedicated hydrogen charging and release module is designed for rapid operation.

Working Principle
The EXPEC 3100 uses detector technology selected according to the target measurement.
Flame Ionization Detection (FID): The sample gas enters a hydrogen flame, where combustible organic compounds generate ions. The detector measures the resulting ion current, which is related to the concentration of hydrocarbons in the sample. FID is used for total hydrocarbon detection and leak screening.
Photoionization Detection (PID): When configured with a PID detector, ultraviolet radiation ionizes compounds whose ionization potentials are suitable for the lamp energy. The resulting electrical signal is used to estimate VOC concentration, with the specified response expressed using isobutylene calibration.
During field inspections, the analyzer measures the sampled gas and displays the result. With the optional EXPEC 3100I handheld controller, operators can control the instrument, associate readings with inspection points, record data, and upload information for LDAR management and VOC source identification.
