背景技术Background technique
由于危险化学品是复杂多样的，有气、固、液态，有机挥发物，水溶液等，特别是化工生产中可能会出现不明化学品及未知成分，通过定性分析可判断化学品的名称、种类，以便为后续的救援工作提供信息，从而可很好地应对化学品突发事故。Because hazardous chemicals are complex and diverse, including gas, solid, liquid, organic volatiles, aqueous solutions, etc., especially in chemical production, unknown chemicals and unknown components may appear. The name and type of chemicals can be determined through qualitative analysis. In order to provide information for follow-up rescue work, so as to respond to chemical emergencies well.
拉曼光谱具有：(1)光源采用激光器，由于激光的单色性很好，激光拉曼光谱峰尖锐、分辨性高。(2)拉曼光谱制样简单，不破坏样品，对于固体样品可直接通过固体支架测定，液体样品可盛放在比色皿中测定，而固体粉末可以放在透明的塑料袋中在固体支架上直接测定或者采用比色皿测定。(3)适用于水溶液体系的测量。(4)拉曼活性的谱线是基团极化率随简正振动改变的关系，故拉曼光谱中只有少量的倍频及组频。所以，在激光拉曼谱图上谱峰清晰，线数较少，往往仅出现基频谱线，易于分析和辨认。(5)检测范围广，包括常见的无机物和有机物，能对生物大分子、天然与合成材料(如碳纳米管、光子晶体等)、矿石、活体动植物组织、水污染样品、化学反应催化剂等等实现检测。(6)可以实时、实地检测，测定速度快，操作方便简单。光谱仪可以采用CCD作为光谱探测器，利用CCD能实现高速的全波段光谱扫描特性，可将光谱扫描时间缩短至几秒甚至更短。Raman spectroscopy has: (1) The light source adopts a laser. Because the monochromaticity of the laser is very good, the peak of the laser Raman spectrum is sharp and the resolution is high. (2) Raman spectroscopy sample preparation is simple and does not destroy the sample. For solid samples, it can be measured directly through the solid support. Liquid samples can be placed in a cuvette for measurement, while solid powder can be placed in a transparent plastic bag on the solid support. Measured directly or using cuvettes. (3) It is suitable for the measurement of aqueous solution system. (4) The spectral line of Raman activity is the relationship between the polarizability of the group and the normal vibration, so there are only a small number of frequency doubling and grouping in the Raman spectrum. Therefore, in the laser Raman spectrum, the spectral peaks are clear, the number of lines is small, and often only the base spectrum line appears, which is easy to analyze and identify. (5) The detection range is wide, including common inorganic and organic substances, and can detect biological macromolecules, natural and synthetic materials (such as carbon nanotubes, photonic crystals, etc.), ores, living animal and plant tissues, water pollution samples, and chemical reaction catalysts. Wait for the detection. (6) Real-time and on-the-spot detection is possible, the measurement speed is fast, and the operation is convenient and simple. The spectrometer can use CCD as a spectral detector, and the use of CCD can realize high-speed full-band spectral scanning characteristics, which can shorten the spectral scanning time to a few seconds or even shorter.
由于拉曼光谱具有上述的优点，故在化学品成分分析中被广泛应用。拉曼光谱(1)对于液体及粉末样品，选择合适的样品池进行测定，利用比色皿盛装样品后放置于样品池中，并合上样品池盖阻止杂散光干扰，连接探头后即可进行测定；(2)对于粉末样品，将其装入透明塑料袋中，之后放置到固体支架上，连接探头，并用探头帽将探头固定，进行测定；(3)对于块状固体，将其表面处理后放置到固体支架上，连接探头，并用探头帽将探头固定，进行测定。但上述取样过程中都需要拆开样品袋，从中取出之后装入透明塑料袋或比色皿。且分析的样品是表面的，无法代表包裹在里面的样品。Because Raman spectroscopy has the above advantages, it is widely used in chemical composition analysis. Raman Spectroscopy (1) For liquid and powder samples, select a suitable sample cell for measurement, use a cuvette to hold the sample and place it in the sample cell, and close the sample cell cover to prevent stray light interference, and then connect the probe. Determination; (2) For the powder sample, put it into a transparent plastic bag, then place it on a solid support, connect the probe, and fix the probe with a probe cap for measurement; (3) For the bulk solid, treat its surface Then place it on a solid support, connect the probe, and fix the probe with a probe cap for measurement. However, in the above sampling process, it is necessary to disassemble the sample bag, take it out and put it into a transparent plastic bag or a cuvette. And the sample analyzed is superficial and cannot represent the sample wrapped inside.
