United States Patent
Patent Number: US20160122234A1 Date of Publication: May 5, 2016 Area of Issue: United States Patent Name: METHOD FOR TREATING SURFACE OF RELEASING CHAMBER IN CONTACT WITH TEST OBJECT
Patent Description：The method for treating the surface of a releasing chamber in contact with a test object reduces the adsorption capacity of the contact surface, thus greatly reducing the adsorption of a test object on the inner wall of the chamber and on the surface of each component in contact with the test object. This method ensures that the tested value of the samples taken from a sampling tube is closer to the actual value of the test object in the chamber. The method effectively improves the testing precision of the releasing chamber.
Patent Number: US009010172B2 Date of publication: Apr.21, 2015 Area of Issue: United States Patent Name: DETECTION SYSTEM AND HUMIDITY DETECTION METHOD FOR DETECTION VOLATILE ORGANIC COMPOUND
Patent Description: The detection system for detecting volatile organic compound includes a clean air adjustment device to introduce clean air into the test chamber to effectively guarantee the test environment and improve detection accuracy. There is a sealing device between the door panel and the door frame of the test chamber, which can greatly improve the sealing effect of the door panel and door frame, and reduce the pollution of the sealing material to the test chamber. The test precision is enhanced. The dynamic and precise control of the humidity is achieved by improving the humidification unit.
Patent Number: US009176506B2 Date of publication: Nov. 3, 2015 Area of Issue: United States Patent Name: LOW PRESSURE AND HIGH-LOW TEMPERATURE TEST BOX CAPABLE OF CONTROLLING HUMIDITY Patent Description: A low pressure and high-low temperature test box capable of controlling humidity comprises a test box body (1), a first heater (2) and a first evaporator (3) which are installed in the test box body (1), a humiture sensor (4) for detecting the humiture inside the test box body (1) and a vacuum manometer (5) for detecting the pressure inside the test box body (1) which are both installed on the test body (1), an air circulation device (6) for circulating the air inside the text box body (1), and a humidity adjusting device (7) which is connected to the test box body(1) and used for adjusting the humidity inside the test box body (1). A vacuum pump (8) for vacuumizing the test box body (1) is also provided on the test box body (1).

As the pretreatment chamber provides standard temperature, humidity and clean environment and ensures balance between temperature, humidity, pressure and VOC emission, it’s extremely suitable for testing pollutant emission rate and emission characteristics of materials and products.
The operation of sample bag type VOC test chamber. First, put materials and products or samples in the testing chamber. Then, adjust the chamber environment, like temperature and humidity, according to actual demands.
This formaldehyde emission test chamber is a great choice to test formaldehyde, acetaldehyde, benzene derivatives and other low boiling point VOCs. However, it’s unsuited for high boiling point VOCs and polar compounds, like tetradecane and 4-phenyl-1-cyclohexene.
