Product Introduction

Product Introduction

This solution is a gas chromatography solution specially designed by Tate Instruments for the detection of residual ethylene oxide (EO) in disposable medical supplies. It is suitable for the detection of residual ethylene oxide in medical supplies such as respirators, medical masks, medical protective clothing, disposable sterilized rubber gloves, disposable sterilized infusion tubes, disposable sterilized syringes, disposable medical needles, etc. with protection levels of N90, N95, KN90, KN95, KN100, etc.

The role and hazards of ethylene oxide: Ethylene oxide is a highly efficient sterilizing agent with characteristics such as high sterilization efficiency, easy volatilization when heated, and is commonly used for sterilization and disinfection of disposable medical and health products. However, ethylene oxide is also a highly carcinogenic substance, and long-term exposure can cause harm to the human body. Therefore, it is necessary to strictly control the residual amount of ethylene oxide in medical and health products to ensure the personal safety of users.

In particular, the current epidemic prevention situation of COVID-19 is still serious. Medical masks and medical protective clothing have become important anti epidemic substances to fight against the epidemic. Many enterprises have begun to switch production of medical masks and medical protective clothing. However, the control level of the production process is different. Some medical masks produced by enterprises have the problem of excess ethylene oxide residue. The state has strict regulations on the amount of ethylene oxide residue in medical masks and protective clothing. Therefore, those masks with excess ethylene oxide are unqualified products and cannot enter the market. In order to control the quality of poor products, medical supplies manufacturing enterprises need professional testing equipment to conduct testing and analysis on their products.

Product Parameters

Product Characteristics

1. New production process, redesigned the air supply path and internal structure inside the instrument, more reasonable component layout, reduced component signal interference, improved detection accuracy, and excellent stability and durability of the equipment.

2. Adopting a 7-inch color touch screen control and a professional chromatograph UI operation interface design, it intuitively reflects the internal temperature values of the injection port, column temperature box, and detector, as well as the values of each detector, and the running time. It has a one click cooling function, and users can set their own detection conditions, making it very convenient to use.

3. The instrument has excellent repeatability. Under the experimental conditions of using an automatic sampler for injection, the repeatability error of the instrument test can reach 2%, which is better than the 3% specified by the national standard.

4. The column temperature box adopts a six channel independent temperature control system, an automatic rear door opening system, a 21 stage 21 platform program temperature rise, fast temperature rise/fall speed, and a temperature control accuracy of 0.1 ℃, making the equipment capable of large-scale sample analysis.

5. The whole machine adopts modular design and can work in parallel with multiple processors. It includes 2 types of injection port modules (capillary column injection port and packed column injection port), 5 types of high-performance detector modules (FID, TCD, ECD, FPD, and NPD), and can be installed with multiple injection ports and detector modules according to customer requirements (customizable six way valve, ten way valve gas injector, top air injector, thermal analysis injector, cracking furnace injector, methane conversion furnace). It can support 3 sets of injection ports and 4 types of detectors, making it convenient for users to upgrade and modify in the later stage.

6. It can be directly connected to the computer and operated through the PC network version chromatography workstation software (supporting 253 units) to achieve program control of the instrument's injection port, column temperature box, and detector temperature rise and fall. Under the condition that the customer is equipped with an automatic injection valve (or automatic sampler), it is possible to achieve a series of testing processes such as unmanned instrument operation, automatic temperature rise and ignition of the instrument, automatic loading method, and automatic calculation of test results, meeting the requirements of online testing.

7. The Internet of Things chromatograph technology, with built-in IP protocol stack, can upload test data to the computer of the on-site laboratory, department heads and superior leaders through the corporate LAN or the Internet, so that each department can monitor the operation of the instrument and test results in real time. It can directly connect with the manufacturer through the Internet to realize remote diagnosis of gas chromatograph, remote program update, etc.

8. It can be integrated with automatic samplers produced by multiple domestic and foreign manufacturers, such as Shimadzu's AOC-20i and Italy's HTA company's HT series high-efficiency gas-phase liquid automatic sampler, to reduce instrument detection errors caused by human factors and improve instrument testing accuracy.
