After the first air passes the clean module to form a second air, the purified second air is then sent out of the main body via the main body air outlet.

A method for operating and diagnosing faults in a laboratory instrument comprising a plurality of subsystems may comprise performing an analytic sequence and a set of diagnostic steps. Such a method may be performed using a diagnostic reagent comprising paramagnetic particles and lacking an antibody component. Such a method may also include evaluating a set of the instrument's subsystems in the opposite of the order in which those subsystems are used during analysis.

An exhaust gas treatment system, comprising an ozone purification system. The ozone purification system comprises an ozone amount control apparatus (209), used to control an amount of ozone so as to effectively oxidize gas components to be treated in exhaust gas, the ozone amount control apparatus (209) comprising a control unit (2091). By means of the present exhaust gas treatment system, particulate matter can be effectively removed from exhaust gas, and the system features a better exhaust gas purification treatment effect.

An air treatment system includes a cyclone filter and an electrostatic filtration system. The cyclone filter may include a cyclone chamber, a cyclone chamber inlet configured to receive air including suspended particulates, and a cyclone chamber outlet configured to output treated air toward a respiratory interface, e.g., a mask or face shield. The cyclone filter produces a rotational airflow that removes at least some particulates from the air in the cyclone filter. The electrostatic filtration system is configured to charge the particulates in the cyclone chamber with a first polarity to produce an electrostatic attraction of the particulates to a particulate removal system charged with an opposite second polarity, to remove additional particulates from the cyclone filter. The air treatment system may also include an ultraviolet purification system to deliver ultraviolet radiation (e.g., UVC radiation) to kill, destroy or otherwise affect organic particulates in the air being treated.
