Gas Headspace Analyzer adopts a new handheld design and is equipped with advanced sensors, which can accurately and conveniently determine O2, CO2, N2 in sealed packaging bags, bottles, cans and other packaging containers. It can store the testing data in the device and transfer to the DK-190 software or third-party software. Effectively testing the atmosphere of the package is necessary steps of mass brand manufacturing.
Features
Testing data can be saved automatically.
Portable design is suitable for test on production lines.
The testing data can be transported to the DK-190 software or the third-party software.
The protective cover of the sampler needle assured the testing safety.
The built-in storage of data can reach 1500 pieces , which can meet the needs of large amount.
Color display with touching function.
It can be used for measurement of oxygen or combination of oxygen and carbon dioxide.
The minimum volume of sampling gas is 3 ml.
Data can be transmitted through Ethernet and USB.
Optional wireless micro-printer.
Principle
The gas is transported to the embedded sensor which calculate the proportion of O2 and CO2 via the exported signal, the test is stopped when the required condition is reached.
Standards
This test instrument conforms to many national and international standards:
ISO 15105-1, ISO 2556, ASTM D1434, JIS K7126-1, GB/T 1038-2000, YBB 00082003.

REAGEChloramphenicol (CAP) ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of chloramphenicol in feed, fish, eggs, honey, meat (beef, chicken and pork), milk, milk powder, serum, shrimp and urine.
The unique features of the kit are:
High recovery (80-105%), rapid (10 - 40 minutes), and cost-effective extraction methods.
High sensitivity (0.05 ng/g or ppb) and low detection limit (0.025 ng/g or ppb) for shrimp, fish and meat samples.
High reproducibility.
A quick ELISA assay (less than 2 hours regardless of number of samples).
Procedure Overview
The method is based on a competitive colorimetric ELISA assay. The CAP antibody has been coated in the plate wells. During the analysis, sample is added along with the CAP-horseradish peroxidase conjugate. If the CAP residue is present in the sample, it will compete for the CAP antibody, thereby preventing the CAP-HRP from binding to the antibody attached to the well. The resulting color intensity, after addition of the HRP substrate (TMB), has an inverse relationship with the CAP residue concentration in the sample.
