Product Introduction The headspace gas analyzer adopts the destructive puncture detection method and is equipped with high-precision oxygen sensors and carbon dioxide sensors to accurately detect the O2 and CO2 content of hollow packaging containers such as packaging bags, bottles, cans, etc. The analysis of the content of the headspace gas in the packaging can make a reasonable judgment on the product quality, the validity of the shelf life prediction, and the rationality of the packaging design. At the same time, it can also be used as a means of packaging tightness testing. It is a better choice for modified atmosphere preservation (MAP, CAP) packaging, large infusion bottles (bags), residual oxygen in the headspace of prefilled needles, residual oxygen detection in vials, and the results of residual oxygen detection for various food and medicines. Nowadays, the headspace gas analyzer has become an important method to check the quality of packaging design and one of the important methods to verify the product shelf life. Our headspace gas analyzer GB-DK can quickly detect O2 in production lines, warehouses, laboratories and other occasions. And CO2 content to guide production.   Test principle The gas in the sample is drawn into the sensor by a vacuum pump. The sensor outputs the current and voltage signals of the O2 and CO2 (optional) concentration in the gas in the sample in real time. The instrument calculates the content of O2 and CO2 in the gas by obtaining the current and voltage signals output by the sensor. After reaching the end conditions of the experiment, the test stops, and the instrument records the concentration of O2 and CO2 in the measured gas in the sample.   Technical parameter Item Parameter Gas to be Measured O2 (standard configuration) CO2 (optional) Measurement Principle Fluorescence optics infrared absorption Measurement Range 0%～25% (for O2) 0%~100% (for CO2) Measurement Accuracy ±0.2% ±2% Sample Size ≥5 mL (at standard atmospheric pressure) (for O2) ≥20 mL (at standard atmospheric pressure) (for CO2) Dimensions 350 mm (L)×330 mm(W)×200 mm(H) Power Supply 220 VAC±10 % 50Hz/120 VAC±10 % 60 Hz Net Weight 5kg    Features 1.Using high-precision sensors, high accuracy, good stability, long-term operation, long service life. Over-range automatic protection function to avoid damage to important sensors when the instrument fails. 2.The needle/probe safety holster is used to ensure safe testing and fast sampling. 3.Oxygen and carbon dioxide can be detected at the same time, and carbon dioxide gas can be selected for analysis according to different user needs. The sampling volume is at least 3 ml. 4.Built-in operating system, the system is equipped with an ARM control system to control the host through a touch screen (testing equipment and control software are combined into one); at the same time, the system can be expanded, such as connecting to the laboratory LIMS system. 5.The software is designed according to the requirements of the computerized system in the new version of the GMP appendix, and users are divided into multiple levels such as operators and administrators (such as administrators, operators, observers, etc. but not limited to these levels). 6.It has the audit trail function, which can realize the audit trail of the system, project operation, and method to ensure the safety and integrity of the test data. 7.Personalize the test report, set the report module that needs to be displayed, and output the report in PDF mode. The micro printer can print test reports in real time.

Product Brief The N600C Carbon Paper Air Permeability Rate Tester is designed and developed in accordance with GB/T 20042.7-2014. Adopting the differential pressure method as its testing principle, it is professionally used for measuring the air permeability rate of various types of carbon paper for proton exchange membrane fuel cells (PEMFC). Testing Principle Based on the differential pressure method, the sample is placed between two fixtures, forming a constant differential pressure on both sides of the sample. Driven by the differential pressure, gas flows from the high-pressure side through the sample to the low-pressure side. The air permeability rate of the carbon paper is calculated based on the transmission flow rate, sample thickness, test area, and test differential pressure.
