Were studied. Phytoncidere was collected by filter flask and air sampler, and analyzed by GC-MS with peak area normalization method.

用抽滤瓶和大气采样器采集薰衣草精气，通过气相色谱－质谱对其进行分析鉴定，峰面积归一法测定各成分GC含量。

The herbicides in the sample was extracted with ethyl acetate. The extract was decanted into a flask through a filter paper, then the filtered solution was concentrated to dry. The dry sample was dissolved and added to 5 mL with acetone-n-hexane (30:70, V/V). It was cleaned up by Florisil, concentrated again. The sample was dissolved and adjusted to 1mL with acetone.

匀浆后的草莓试样用乙酸乙酯进行提取，提取液经滤纸过滤后收集，再浓缩蒸干，用丙酮：正己烷(30：70， V/V)溶液溶解至5ml，经Florisil固相萃取柱净化，吹干后用丙酮定容，供气相色谱－质谱联用仪进行测定。

A GC/MS method was developed to compare lipophilic compounds of fruit and peel of Citrus grandis Tomentosa .

方法应用气相色谱-质谱联用技术对化橘红的皮和胎的脂溶性化学成分进行分析。

Under these conditions, twenty compounds in the volatile oil of garlic were isolated and identified, and the content of each was determined.

实验确定了气相色谱-质谱法分析大蒜油的条件，并对大蒜挥发油的化学成分进行了定性分析，共鉴定出20种物质。

The composition of fatty acids in oil and fat was detected by gas chromatography and fire ionization detector at home,however,the reports about the separation and detection of triglyceride in oil and fat were very little.

对油脂的分析，国内主要是采用气相色谱分离和火焰离子化检测器检测其中的脂肪酸组成，而对甘油酯的分离和检测报道较少，国外研究者利用色谱和质谱联用技术对甘油三酯的分离和检测做了大量的研究。

In this research, large volume stainless pots, high－quality pottery pots and enamel pots, instead of traditional small volume pottery pots, were used in storing several kinds of fresh liquor like "Shuanggou Liquor" etc.and the analysis of stored liquor by gas chromatography and atomic absorption spectrum indicated that the application of large volume stainless containers, instead of the traditional pottery pots, could not only advance liquor aging , produce flavour and remove precipitate, develop soft liquor style, stabilize and improve liquor quality,harmonize the balance of components , decrease liquor loss and liquor storage space,but also promote oxidation , reduction, esterification and molecular hydrogen bond association in the process of liquor storage.

对&双沟酒&等各香型酒，利用大容器的不锈钢罐、优质陶缸和搪瓷罐代替传统小容积陶坛或陶缸贮存新酒作了试验研究。采用气相色谱和原子吸收光谱对贮酒分析，得出采用不锈钢等大容器代替传统小陶罐贮存酒，不但可使酒在贮存过程中进行氧化、还原、酯化和分子氢键缔合作用，促进酒体老熟去杂增香，使酒体柔和老熟、成分平衡协调，稳定和提高酒质；而且还可以降低酒的损耗和减少贮酒库占地面积。孙悟
