Jiqun JQ-CM01 Automated Gas Sampling Bag Cleaner

Overview

The Jiqun JQ-CM01 Automated Gas Sampling Bag Cleaner is an engineered solution for laboratories performing ambient air, stack emission, or volatile organic compound (VOC) monitoring where rigorous pre-use conditioning of flexible gas sampling containers is mandatory. It operates on a dual-mode pneumatic principle—applying precisely controlled negative pressure (vacuum) followed by positive-pressure inert gas purging—to remove residual moisture, oxygen, and trace contaminants from aluminum-laminated foil bags, PTFE (Teflon®-lined) sampling bags, rubber bladder samplers (e.g., “ballon”-type gas bulbs), and glass/plastic syringes used in EPA Method TO-14A, ISO 16017-1, and EN 13649-compliant workflows. Unlike manual rinsing or static purge methods, the JQ-CM01 delivers reproducible, auditable cleaning cycles with programmable vacuum depth, dwell time, and purge repetition—critical for minimizing memory effects and ensuring analytical accuracy in GC-FID, GC-MS, and FTIR-based gas analysis.

Key Features

• 48 independently addressable cleaning ports enable parallel processing of mixed-format sampling devices—no batch segregation required; users connect only the ports needed per run.
• Programmable dual-stage cleaning protocol: vacuum evacuation (–100 to 0 kPa gauge) followed by positive-pressure inert gas flush (0 to +100 kPa gauge), both fully adjustable via touchscreen interface.
• Real-time cycle monitoring with timestamped log display showing applied pressure, elapsed time per stage, and total cycle count—supports GLP documentation requirements.
• Quick-release silicone tubing system (ISO 8536-4 compliant) allows tool-free replacement without disassembling manifolds; tubing meets USP Class VI biocompatibility standards.
• Robust stainless-steel frame with IP54-rated enclosure ensures durability in shared lab environments; integrated thermal cutoff prevents overheating during extended operation.

Sample Compatibility & Compliance

The JQ-CM01 accommodates standard gas sampling formats including 0.5–10 L aluminum-laminated foil bags (e.g., SKC, Supelco, Restek), PTFE-coated Tedlar®-equivalent bags, elastomeric bulb samplers (natural rubber or butyl), and 10–100 mL gas-tight glass syringes. All cleaning parameters adhere to the preconditioning recommendations in ASTM D5502–22 (“Standard Practice for Preparation of Gas Sampling Bags”) and align with QA/QC protocols referenced in EPA Compendium Method TO-15 and ISO 16017-2 for VOC measurement. While the unit itself is not CE-marked or FDA-listed, its operational logic supports 21 CFR Part 11–compliant data integrity when integrated with validated LIMS or ELN systems via optional RS-232/USB logging output.

Software & Data Management

The embedded Chinese-language touchscreen controller provides intuitive setup of up to 16 user-defined cleaning profiles, each storing vacuum setpoint, purge pressure, hold duration, and cycle repetitions. System logs—including date/time stamp, operator ID (manually entered), and pass/fail status per port—are exportable as CSV files via USB drive. For regulated environments, third-party SCADA or LabWare LIMS integration is supported through ASCII serial command protocol (Modbus RTU optional). Audit trail functionality includes automatic timestamping of all parameter changes and cycle initiations—meeting minimum ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate) principles for raw data recording.

Applications

• Ambient air monitoring networks requiring daily bag reconditioning prior to passive sampler deployment.
• Stack testing laboratories performing Method 18 or EPA Method 25A compliance measurements.
• Industrial hygiene labs validating workplace exposure limits (OELs) using grab-sampling protocols.
• Research facilities conducting stable isotope ratio analysis (e.g., δ¹³C-CH₄) where carbon background must be <0.1 ppmv.
• Calibration labs maintaining certified reference gas standards in reusable containers.

FAQ

Does the JQ-CM01 support automated inert gas switching (e.g., N₂ → He)?

No—the unit requires external gas selection upstream of the inlet manifold; it does not include solenoid-valve-based multi-gas routing.
Can cleaning validation data be exported in PDF format?

CSV export is native; PDF generation requires post-processing via connected PC software or LIMS integration.
Is the touchscreen firmware upgradable in the field?

Yes—firmware updates are delivered via USB stick and installed through the maintenance menu with password protection.
What maintenance intervals are recommended for the vacuum pump?

Oil-lubricated rotary vane pump requires oil change every 500 operating hours; dry diaphragm pump option available upon request (model suffix -D).
Does the system meet explosion-proof requirements for Zone 1 hazardous areas?

No—it is rated for general laboratory use only (non-classified environment); intrinsic safety certification is not provided.
