Infrared spectroscopy (IR spectroscopy) is considered one of the most important physical measurement techniques and is used in almost all areas of chemical analysis due to its versatility and reliability. A major advantage of IR spectroscopy over other measurement techniques is its ease of sample handling: even very small amounts of substance are sufficient to obtain unambiguous measurement results. In terms of the measurement method, gases, liquids and solids can be measured, but the focus of the applicant will be on measurements of solids. The instrument we are looking for will be used for a variety of different geoscientific applications and must therefore be able to measure with high reliability and accuracy. In addition to standard applications in the mid-IR range, applications in the far IR range (e.g., analyses of carbonate samples) make it necessary for the instrument to have spectral range extension capabilities. For measurements on polymer granules (e.g. microplastics), an ATR (attenuated total reflection) unit is required in the sample chamber. This also allows shaped solid pieces as well as powders and thin films to be measured. Due to the often extremely small geoscience sample sizes coupled with the need for spatially resolved analyses, the basic Fourier transform infrared (FT-IR) spectrometer must be combined with a high-end IR research microscope, and in order to perform qualitative and quantitative analyses, reflectance and transmission measurements must be possible. Since the already foreseeable demand for automated IR spectroscopic high-throughput analyses in reflection and transmission modes is constantly growing, the basic instrument must furthermore be expanded by a microplate reader. This will allow up to 96 samples to be measured without manual sample changes.

红外光谱被认为是最重要的物理测量技术之一，由于其通用性和可靠性，几乎被用于化学分析的所有领域。与其他测量技术相比，红外光谱的一个主要优点是易于处理样品：即使非常少量的物质也足以获得明确的测量结果。在测量方法方面，可以测量气体、液体和固体，但申请人的重点将放在固体的测量上。我们正在寻找的仪器将用于各种不同的地球科学应用，因此必须能够以高可靠性和准确性进行测量。除了中红外范围的标准应用之外，远红外范围的应用（例如，碳酸盐样品的分析）使得仪器必须具有光谱范围扩展能力。对于聚合物颗粒（如微塑料）的测量，样品室中需要ATR（衰减全反射）单元。这也允许形状的固体件，以及粉末和薄膜的测量。由于地球科学样本通常非常小，再加上对空间分辨率分析的需求，基本的傅里叶变换红外（FT-IR）光谱仪必须与高端红外研究显微镜相结合，为了进行定性和定量分析，反射率和透射率测量必须是可能的。由于对反射和透射模式的自动化红外光谱高通量分析的需求不断增长，基本仪器必须进一步扩展微孔板读取器。这将允许多达96个样品进行测量，而无需手动更改样品。
