    • A folding mesh chair includes a seat and a backrest carried between opposite frame sides. The chair has an unfolded seating position in which the seat pivots to extend from the frame sides and bottoms of front and rear legs move apart, and a folded position in which the seat pivots toward the frame sides and the front and rear legs move together. One or both of the seat and the backrest have a continuous sheet of flexible and elastic mesh or patterned open texture plastic held across and substantially covering an opening in an all-plastic hoop fixed between the frame sides. The hoop includes inner and outer plastic mating hoops with the mesh extending over an outer perimeter of the inner hoop and into an interface between the inner and outer hoops.
    • 折叠网椅包括座位和靠在相对的框架侧之间的靠背。 椅子具有展开的就座位置,其中座椅枢转以从框架侧面延伸,前后腿的底部移动分开,并且座椅朝向框架侧部枢转并且前后腿部一起移动的折叠位置。 座椅和靠背中的一个或两个具有连续的柔性和弹性网格片或图案化的开放纹理塑料,其保持横跨并且基本上覆盖固定在框架侧之间的全塑性环箍中的开口。 箍包括内部和外部塑料配合箍,其中网状物在内箍的外周延伸并且进入内圈和外箍之间的界面。

    • A method for analyzing analytes from a sample introduced into a Spectrometer by generating a pseudo random sequence of a modulation bins, organizing each modulation bin as a series of submodulation bins, thereby forming an extended pseudo random sequence of submodulation bins, releasing the analytes in a series of analyte packets into a Spectrometer, thereby generating an unknown original ion signal vector, detecting the analytes at a detector, and characterizing the sample using the plurality of analyte signal subvectors. The method is advantageously applied to an Ion Mobility Spectrometer, and an Ion Mobility Spectrometer interfaced with a Time of Flight Mass Spectrometer.

    • The present invention relates generally to an apparatus and method for separating high molecular weight molecules from low molecular weight molecules. More specifically, the invention relates to the use of microdialysis for removal of the salt (low molecular weight molecules) from a nucleotide sample (high molecular weight molecules) for ESI-MS analysis. The dialysis or separation performance of the present invention is improved by (1) increasing dialysis temperature thereby increasing desalting efficiency and improving spectrum quality; (2) adding piperidine and imidazole to the dialysis buffer solution and reducing charge states and further increasing detection sensitivity for DNA; (3) using low concentrations (0-2.5 mM NH4OAc) of dialysis buffer and shifting the DNA negative ions to higher charge states, producing a nearly 10-fold increase in detection sensitivity and a slightly decreased desalting efficiency, (4) conducting a two-stage separation or (5) any combination of (1), (2), (3) and (4).
    • 本发明一般涉及从低分子量分子中分离高分子量分子的装置和方法。 更具体地,本发明涉及使用微量透析从ESI-MS分析的核苷酸样品(高分子量分子)中除去盐(低分子量分子)。 通过(1)增加透析温度从而提高脱盐效率和提高光谱质量,提高本发明的透析或分离性能; (2)向透析缓冲液中加入哌啶和咪唑,降低电荷状态,进一步提高DNA的检测灵敏度; (3)使用透析缓冲液的低浓度(0-2.5mM NH 4 OAc),并将DNA负离子转移到较高的电荷状态,检测灵敏度增加近10倍,脱盐效率稍微降低,(4) 级分离或(5)(1),(2),(3)和(4)的任何组合。
