Gastec P-130-H Permeation Tube Vinylidene Chloride

Description

Precision Calibration with Gastec P-130-H Permeation Tube Vinylidene Chloride

Ensuring the accuracy of gas analysis requires a consistent and verifiable source of calibration gas. The Gastec P-130-H Permeation Tube Vinylidene Chloride is designed to meet this need by utilizing a permeation method to generate specific gas concentrations. The tube serves as a primary standard for generating calibration gas, allowing for the precise adjustment of analytical equipment.

Because permeation tubes have individual differences in permeation rates, the actual controlled range may differ slightly from the standard concentration ranges, providing a custom-calibrated experience for high-stakes testing. This method is superior for creating low-concentration gas mixtures that are difficult to store in traditional gas cylinders. Its robust design allows for professional use in systems requiring stable, liquified chemical components for accurate chemical analysis.

Specifications

Based on the official Gastec technical documentation for this series:

Model Number: P-130-H.
Chemical Component: Vinylidene Chloride.
Concentration Range: 0.16 – 8.2 ppm.
Generation Method: Permeation tube.
Note on Precision: Actual ranges may differ slightly due to individual differences in permeation rates.

Features

Vinylidene Chloride Specific: Engineered specifically to generate a certified concentration of vinylidene chloride (CAS 75-35-4), a volatile organic compound (VOC) of interest in industrial hygiene and environmental monitoring.
Gravimetric Permeation Technology: Contains liquid VDC sealed within a precisely engineered polymer tube (e.g., Teflon®/FEP). The compound permeates through the tube walls at a constant, temperature-dependent rate, measured gravimetrically to provide a certified emission rate (ng/min or µg/min).
NIST-Traceable Primary Standard: Each tube is individually weighed and certified, providing a NIST-traceable or ISO 17025-accredited emission rate. This ensures the highest level of accuracy and metrological traceability for compliance and quality assurance.
Constant & Stable Output: When maintained at a constant temperature in a dedicated thermostat (oven), it produces an exceptionally stable and repeatable gas concentration over its entire service life.
Cylinder-Free & Safe Handling: Eliminates the need for high-pressure VDC gas cylinders, significantly reducing safety risks, regulatory burdens, and costs associated with storage, transport, and disposal of toxic gas cylinders.
Long Operational Life: Designed for extended use, typically offering a service life of one to two years, providing a cost-effective and continuous calibration source.

Applications

Calibration of PID Detectors: Primary standard for calibrating and verifying the response of Photoionization Detectors (PIDs) used for VOC leak detection and industrial hygiene surveys, specifically for VDC.
Gas Chromatograph (GC) Calibration: Used to prepare precise standard gas mixtures for calibrating GC and GC/MS systems in environmental, pharmaceutical, and chemical analysis laboratories.
Industrial Hygiene & Workplace Monitoring: Generates known concentrations for calibrating personal and area monitoring equipment used to assess worker exposure to vinylidene chloride in manufacturing (e.g., PVC production) or chemical handling facilities.
Environmental Air Quality Analysis: Provides traceable standards for calibrating continuous emission monitoring systems (CEMS) or ambient air analyzers measuring VDC.
Sensor Development & Testing: Serves as a precise and adjustable vapor source for evaluating the performance, sensitivity, and linearity of new chemical sensors and detection technologies.
