Phosalone, malathion and diazinon were analyzed in corn oil using solid phase extraction (SPE)with lanthanum silicate as a new solid sorbent followed by gas chromatography with nitrogenphosphorus detection (GC-NPD). The efficiency of different eluents (methanol, dichloromethane,ethyl acetate, dichloromethane — ethyl acetate (1:1) and ethyl acetate — methanol (1:1)) werecompared for elution of o...

The detection of toxic metals is indispensable for water safety. In this paper, a small molecule aggregation-induced emission (AIE) with barbiturate group was synthesized. It combined mercury ions to form stable metal complex so as enhance the color solution achieve visualization ion detection. fluorescent showed good selectivity and anti-interference ability had low limit (DL = 22.27 nM) ion.

Liquid matrix-assisted laser desorption/ionization (MALDI) allows the generation of predominantly multiply charged ions in atmospheric pressure (AP) MALDI ion sources for mass spectrometry (MS) analysis. The charge state distribution of the generated ions and the efficiency of the ion source in generating such ions crucially depend on the desolvation regime of the MALDI plume after desorption i...

We propose the use of trapped ions for detection millicharged dark matter. Millicharged particles will scatter off ions, giving a signal either in individual events or overall heating rate ions. Ion traps have several properties that make them ideal detectors such signal. First, ion demonstrated significant isolation from environment, greatly reducing background and event rates. Second, can low...
