  • Publication number: 20140326042
    Abstract: Provided are sampling pumps and gas analyzers using the sampling pumps. The sampling pump may include at least one reciprocating pump set and a control system. Each reciprocating pump set can include two reciprocating pumps. The control system can output drive signals for controlling reciprocating drawing and compressing operations of the reciprocating pumps, where the control system may be designed to output the drive signals that cause the two reciprocating pumps within the same set to provide opposing impact directions at the same time.

  • Patent number: 8092705
    Abstract: The present invention provides a simple method for introducing magnetic particles into a polymer for further preparing a magnetic polymer, the method using the capability of polymer to absorb Fe3+ and other divalent metal ions M2+, adding alkali immediately each time after absorbing Fe3+ or M2+, thereby generating hydrated oxide of the Fe3+ and hydrated oxide of the divalent metal ions in sequence inside the polymer, and then heating, so that the hydrated oxide of the Fe3+ and the hydrated oxide of the divalent metal ions are transformed into magnetic particles MFexOy, where M may be Fe2+, Zn2+, Mg2+, Cu2+, Ca2+, Ba2+, Sr2+, Ni2+, Co2+, Mn2+ and the like, and x=1.0˜2.0; y=3.0˜4.0. Compared with the prior art method, the present one is simpler, wider in application, and more operable.
