[Determination of six amide herbicide residues in soil by QuEChERS-gas chromatography-mass spectrometry].

Se pu = Chinese journal of chromatography
A method was developed for the determination of six amide herbicides, such as acetochlor, alachlor, metolachlor, metazachlor, butachlor and pretilachlor, by QuEChERS-gas chromatography-mass spectrometry. The soil samples were extracted by 10 mL aceto...

[Determination of total phthalates in perfume and their exposure assessment].

Se pu = Chinese journal of chromatography
A novel method for rapid screening of phthalates (PAEs) in perfumes was developed. The PAEs were hydrolyzed to phthalic acid (PA), and the PA in the acidified solution was extracted with tributyl phosphate (TBP) which was detected by high performance...

[Determination of oxygenates in methanol-to-olefin gasoline byproducts and methanol-to-gasoline product with solid phase extraction-gas chromatography].

Se pu = Chinese journal of chromatography
Silica solid phase extraction (SPE) column was used for sample pretreatment to enrich the target analytes and simplify background. Due to its high efficiency, reliability and simplicity, the technique has been widely used in many fields. The byproduc...

[Determination of flavor compounds in foxtail millet wine by gas chromatography-mass spectrometry coupled with headspace solid phase microextraction].

Se pu = Chinese journal of chromatography
To comprehensively understand flavor compounds and aroma characteristics of foxtail millet wine, extraction conditions were optimized with 85 μm polyacrylate (PA), 100 μm polydimethylsiloxane (PDMS), 75 μm carboxen (CAR)/PDMS and 50/30 μm divinylbenz...

[Determination of inorganic anions and gluconate by two-dimensional ion chromatography].

Se pu = Chinese journal of chromatography
A new two-dimensional ion chromatography method was developed to parallelly analyze two different types of samples with the application of valve switching technology-suppressed conductivity and pulsed amperometric analysis system, for concurrent dete...

[Simultaneous determination of four aflatoxins in Citrus reticulatablanco by ultra performance liquid chromatography coupled with immunomagnetic beads for enrichment and purification].

Se pu = Chinese journal of chromatography
Immunomagnetic beads (IMBs) were formed by coupling the ProtElut NHS (N-hydroxysuccinimide) magnetic beads and anti-aflatoxins monoclonal antibody. The synthesized IMBs presented uniform size, good magnetic property and specific selectivity. In this ...

[Determination of rutin, quercetin and kaempferol in Althaea rosea (L) Gavan for Uyghur medicine by high performance liquid chromatography].

Se pu = Chinese journal of chromatography
Uyghur medicine is one important part of the national medicine system. Uyghur medicine modernization, namely the study of effective components with modern technologies, is the only way for the scientification, standardization, and industrialization o...

[Simultaneous determination of four drugs for kidney diseases in urine by high performance liquid chromatography].

Se pu = Chinese journal of chromatography
A high performance liquid chromatographic (HPLC) method was proposed for the simultaneous determination of four drugs for kidney disease, enalapril, triamterene, furosemide and valsartan. After proteins being removed by acetone precipitation method, ...

[Determination of imidaclothiz in tea by QuEChERS cleanup and liquid chromatography-tandem mass spectrometry].

Se pu = Chinese journal of chromatography
The method for the determination of imidaclothiz residue in tea by liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed. The imidaclothiz in tea was extracted by acetonitrile and purified by QuEChERS with PSA (primary secondar...

[Determination of six anticoccidials in chicken using QuEChERS combined with ultra high liquid chromatography-high resolution mass spectrometry].

Se pu = Chinese journal of chromatography
An ultra high liquid chromatography-Q Exactive orbitrap mass spectrometry multi-residue method has been developed for the determination of six anticoccidials residues (dinitlmide, nicarbazin, diclazuril, toltrazuril, monensin and salinomycin) in chic...
