Laminates are combinations of polymers that combine the benefits and properties of the various polymers used in the laminate to create a better material. Polymer laminates have a multitude of uses including packaging for food and other products. Laminates act as moisture and/or oxygen barriers and as such are commonly used to protect foods and chemicals. Analysis of laminates is often required for quality control and to determine laminate adhesion problems.

对于低浓度气体或蒸汽化合物的FT-IR分析，通常需要高信噪比测量。此外，某些气体样品的测量可能会受到仪器中存在的大气水蒸气和二氧化碳的影响，即使是通过氮气净化。由于NO气体的吸收带在水蒸气区，而二氧化氮、二氧化碳和CO气体的吸收带靠近二氧化碳吸收区，因此分析尤其困难。使用全真空仪器系统，可以完全消除光路中的水蒸气和二氧化碳，即使在低浓度下也可以完成这些气体成分的测量。

本申请说明中介绍的FT/IR-6000系列全真空气体分析系统在样品室中集成了一个特殊的气室，使整个光路在气室就位的情况下保持在全真空下。该全真空模型使得即使在0.2ppm水平下也能够定量H2O的浓度。

Figure 1: ATR-500/Mi?ATR crystal plate (Upper right: Prism and liquid cell) Characterized by wavelengths longer than the mid-infrared region, the far-infrared region is also referred to as the terahertz region. In recent years, this region has been used to evaluate crystal polymorphs for pharmaceuticals and semiconductor device materials, as well as for archaeological research applications, including the study of inorganic pigments. Light in the far-infrared region (terahertz waves) corresponds to hydrogen bonding and Van der Waals forces believed to hold the key to an understanding of the functional

Gas Analysis System using Full Vacuum Type FT/IR (Trace amount of H2O in N2 gas) (1/2) No. 230TR0187-E The analysis of low concentration gases using long pathlength gas cells has been reported previously, however, it can be difficult to accurately quantitate gases at low concentrations when the absorption peaks of the target gas overlap with the peaks of atmospheric water vapor or, when the target gas itself is H2O or CO2, which are presnet in the atmosphere. This is because even with a vacuum FT-IR instrument, it was not possible to evacuate the sample chamber with the long pathlength cell present. The full vacuum gas analysis system introduced in this application note has a special gas cell integrated into the sample chamber, allowing the entire light path to remain under full vacuum with the gas cell in place. This full vacuum model makes it possible to quantitate concentrations of H2O even at the 0.1 ppm level. For the measurement, there are separate vacuum lines for evacuation of the FT-IR instrument and the gas cell, with independent evacuation capability for the separate components. Adding a vacuum gauge to the gas cell makes it possible to control extremely

用NIR成像法鉴定药片

与中红外分析相比，近红外（NIR）光谱具有独特的能力，中红外分析通常需要大量的样品制备才能获得可识别的光谱。因此，根据所需的分析，NIR可用于特定样品区域的非破坏性分析或提供较大样品区域的平均值。近年来，近红外光谱已被广泛用于生物样品的检测以及食品和医疗产品的质量控制/分析。漫反射技术是这种方法的理想选择，因为样品处理极其简单，因此可以通过使用使用近红外漫反射创建的搜索数据库来快速识别非法药物，如MDMA。

FTIR光谱已被广泛用于评估蛋白质如VHH抗体的结构。α-螺旋和β-薄片的二次结构估计（SSE）可以快速而容易地进行。在本申请说明中，我们讨论了FTIR测量与新型冠状病毒（SARS-CoV-2）结合的VHH抗体冷却过程和反复冷冻和解冻引起的二级结构变化的结果。 关键词：New冠状病毒、SARS-CoV-2、COVID-19、生物制药、抗体药物、生物类似物、VHH抗体、HOS、二级结构、三级结构

Introduction Near-Infrared (NIR) spectroscopy has unique capabilities as compared to mid-infrared analysis which can often require extensive sample preparation to obtain an identifiable spectrum. As such, NIR can be useful for the non-destructive analysis of a specific sample area or provide an average of a larger sample area, depending upon the required analysis. In recent years, NIR spectroscopy has been widely used for the examination of biological samples and quality control/analysis of food and medical products. The diffuse reflectance technique is ideal for this method due to extremely simple sample handling such that rapid identification of illegal drugs, such as MDMA, can be accomplished by using a search data library created using NIR diffuse reflectance.

The use of near-infrared (NIR) spectroscopy in the pharmaceutical industry has grown rapidly in the past decade. The IMV-4000 Infrared Multichannel Viewer integrated with a NIR capable FT/IR- 4000 or FT/IR-6000 instrument enables NIR Imaging of pharmaceutical tablets, a valuable tool in the estimation of tablet properties, offering measurement data with high specificity and sensitivity. The obtained data can be exported into the Principal Component Analysis (PCA) software for the estimation of tablet characteristics. Instrument: FTIR-6200 with IMV-4000 CaF2 beam splitter, NIR source, etc

Analysis Example by Vacuum Model FT/IR (1) Measurement of Silicon Wafer (1/1) No. 220TR0164-E Due to the high refractive index of silicon wafer samples, there is a correspondingly high reflectance from the sample. If the sample is placed directly in the sample compartment, vertical to the incident source beam, the reflection of the source returns to the interferometer, is reflected by the beamsplitter and then illuminates the sample again. As a result, the sample pathlength of the sample measurement is different from the background measurement and excessive noise is observed due to the atmospheric water vapor, even with a purged instrument. While it is possible to adjust the angle of the sample with respect to the incident source illumination, using an evacuated FT-IR instrument allows measurement of the sample vertical to the incident illumination without
