sample evaporator

The method consists of ultrasonic extraction of colistin sulfate in feed sample, condensation of the extraction liquid by rotary evaporator, and determination by HPLC.

该方法首先用超声波法提取饲料中的硫酸粘杆菌素，通过旋转蒸发将提取液浓缩后，利用HPLC进行检测。

In a resistance thermal vacuum evaporator with a special heater ( coolant) holder, which can control the sample substrate temperature, Au and In 2O 3 films were deposited on glass slides by a thermal and an activated reactive evaporation technique, respectively.

用带特殊热（冷）阱的可控制基片温度的电阻加热式真空蒸镀薄膜装置，把吸收透明导电薄膜Au和In2O3分别通过热蒸镀和活化反应淀积在玻璃基片上。

After removing ether in the extract in a rotary evaporator, a transparent, yellow liquid with special fragrance was obtained, which contains the volatile components of the sample. The recovery was about 6.5%.

用旋转蒸发器除去乙醚后即得到含有试样中挥发组分的透明的黄色液体，收得率为6.5%，应用GC/MS法对黄色液体的组分进行定性和定量分析。
