Ethylene oxide residue tester gas chromatography Test principle: In the sealed bottle, the volatile ethylene oxide molecules escape from the liquid phase into the gas phase on the liquid surface. At a certain concentration, the ethylene oxide molecules reach dynamic equilibrium between the gas and liquid phases. The concentration of ethane in the gas phase is directly proportional to its concentration in the liquid phase. The concentration of ethylene oxide in the gas phase is measured by a gas chromatography instrumentation to determine the residual amount of ethylene oxide in the mask. Ethylene oxide residue tester indicator function: Ethylene oxide is a toxic carcinogen, and the residual amount of ethylene oxide in masks is an important indicator for verifying the hygiene and health of masks. The residual amount of ethylene oxide in the mask cannot exceed 10μg/g.

Medical Face Mask Flame Resistance Tester Test principle: Pass the mask through a flame with a temperature of 800°C and a flame height of 40mm at a speed of 60mm/s. When the mask is completely out of the flame, measure the afterburning time and smoldering time of the mask. So as to achieve the purpose of judging whether the mask is flammable. Flame retardant performance index function: The flame retardant performance is an important indicator of whether the mask has undergone flame retardant finishing. The masks we wear should be made of non-flammable materials to ensure that the person wearing the mask will not burn the face due to the burning of the mask when it accidentally approaches the fire source. GESTER Mask testing machine recommendation: Mask Flame Retardant Tester GT-RA06

Respiratory Resistance Tester Test principle: By simulating the exhalation of the human body and the airflow generated by inhalation, the exhalation resistance and inhalation resistance generated when wearing the mask are detected, so as to determine whether the person wearing a mask with a certain filtering efficiency affects the normal breathing of the human body purpose. Expiratory resistance, inspiratory resistance indicators: Exhalation resistance, inhalation resistance index function Exhalation resistance and inhalation resistance are one of the important indicators that represent whether the human body will have respiratory discomfort when wearing a mask. If the resistance is too large, it will affect the normal breathing of the human body, and the more unsuitable for wearing, the masks with exhalation resistance greater than 250Pa and inhalation resistance greater than 350Pa are all unqualified products.

Synthetic Blood Penetration Resistance Tester Test principle: The air pressure generated by the air compressor simulates the blood pressure of the human body (10.6KPa-16.0KPa). 2mL of synthetic blood with a surface tension of (0.042±0.002) N/m is sprayed on the surface of the mask to detect whether the mask can prevent blood from penetrating. The role of Mask Synthetic Blood Penetration Tester indicators: When working with medical staff, especially when rescuing a patient or performing a surgical operation, the patient's blood will be splashed out, and blood is often the carrier of virus transmission, so the mask must have anti-blood penetration performance, which can To a certain extent, prevent the spread of viruses.

Mask Particulate Filtration Efficiency Tester Test principle: The aerosol generator converts the 2% sodium chloride solution into particles with a concentration of 30mg/m³ and a diameter of 0.075μm. According to different standards, the particles are transported into the closed cavity by adjusting different air flows. The test starts when the concentration of the upper cavity and the lower cavity of the cavity reach equilibrium, because particles will continuously enter the cavity, so when the filter material is filtered, the concentration of the lower cavity will decrease, and the concentration of the upper cavity will remain at equilibrium status. Therefore, the computer will calculate the filtration efficiency according to the concentration difference between the upper and lower chambers. Filtration efficiency index role Filtration efficiency is to determine whether the filter material of a mask has the function of filtering particles and bacteria; the higher the filtration efficiency, the better the protective effect of the mask.
