The neutral/basic fraction was furthermore separated into 4 fractions using silica gel normal phase chromatography, and each fraction was then concentrated and analyzed using gas chromatography-mass spectrometry. In comparison with the pure standards and the retention indices reported in the literature, a total of 302 volatile compounds were identified in Changyu XO brandy, including 30 alcohols, 35 aldehydes and ketones, 20 carboxylic acids, 104 esters, 24 substituted benzenes and derivatives, 14 phenolic derivatives, 14 acetals, 16 furan derivatives, 22 terpenic and norisoprenoidic derivatives and 23 others.

实验先采用液-液萃取方法提取张裕XO级白兰地的挥发性成分，然后将酸性成分与碱性和中性成分分离，再采用柱色谱分离手段将其分离为若干个级分并浓缩，采用气相色谱-质谱、标准品比对、保留指数值比较等方法对分离得到的各级分中的成分进行了鉴定，在白兰地中共鉴定出302种挥发性成分，包括醇30种、醛酮类35种、酸类20种、酯类104种、苯同系物及其衍生物24种、酚类14种、缩醛14种、呋喃类16种、萜烯类22种和其他物质23种。

The proteins in milk and dairy products were mostly eliminated by the precipitators. Three aseptics and two sweeteners were separated on a C18 column with the mobile phase of methanol -0.05mol/L potassium dihydrogen phosphate under gradient elution. With a diode array detector, acesulfame, benzoic acid, and sorbic acid were detected at 230 nm and sodium saccharin and aspartame were detected at 210nm.

通过加入适量沉淀剂除去样品中绝大部分蛋白质后，采用C18色谱柱分离，以甲醇－0.05mol/L磷酸二氢钾溶液为流动相梯度洗脱，用二极管阵列检测器于230nm波长处检测安赛蜜、苯甲酸和山梨酸，于210nm波长处检测糖精钠和阿斯巴甜。

The transport of atrazine in soil was investigated with soil column experiments.
