They grow their bacteria on a stainless steel plate, and use a laser to vaporise their signalling molecules, feeding these into a mass spectrometer to catalogue the molecules present.

他们在一个不锈钢培养皿里培育细菌，然后用激光蒸发它们的信号分子，把这些分子导入到质谱分析仪中并记录他们的状态。

The fibres were replaced at regular intervals over the course of seven days and taken away for analysis by a device called a gas chromatograph-mass spectrometer.

在七天的实验里，每隔一定时间就要更换一次纤维，然后用一种叫做气相色谱质谱联用仪的装置提取以供分析。

These samples were run through a mass spectrometer - a device that effectively measures all the masses of the chemical compounds in the breath.

BBC: Exhaled breath is unique fingerprint

As more drops are sprayed on the same spot, some of this film is scattered and sucked into a mass spectrometer, which can identify the molecules collected.
