拉曼光譜分析儀 – 常見問答

A Raman spectrometer is an analytical instrument used to measure the Rayleigh scattering effect, which is a type of light scattering that occurs when light interacts with matter. Raman analyzers are powerful tools for non-destructive analysis and characterization of a wide range of materials, providing valuable insights into their molecular composition and structure.

A Raman spectroscopy machine consists of three components: the laser, the spectrometer itself, and the sampling interface. In a Raman spectrometer from Metrohm, all three components are developed and manufactured by Metrohm Spectro.

A Raman laser has a narrow linewidth, small form factor, low power consumption, and an extremely stable power and exciting wavelength output. The precision-engineered Raman spectrometer is characterized by a high resolution, low noise, small form factor, and low power consumption. The sampling interface allows for precise, easy, and safe sampling. Metrohm offers various sampling interfaces and attachments to automate sampling in any situation from trace detection to through container analysis to data collection from across the room.

The laser beam of the Raman analyzer is typically directed onto the sample, and the Raman scattered light is collected and directed into the spectrometer. The spectrometer disperses the scattered light into its different wavelengths, which are then detected by a sensitive detector.

The resulting Raman spectrum, which represents the intensity of scattered light at different wavelengths, provides information about the molecular vibrations and can be used to identify substances or study molecular interactions.

Raman spectrometer instrumentation is successfully applied for identifying unknown materials and verifying or quantifying known materials. Raman spectroscopy is a non-destructive analysis technique that allows for fast and safe analysis, as no sample preparation is needed and, in some cases, samples can even be analyzed in their original packaging.

Applications of Raman spectroscopy include raw material verification, quality control of incoming goods, identification and analysis of active pharmaceutical ingredients (APIs), additives and excipients, and identification of illicit or counterfeit substances such as drugs.

Handheld Raman systems are small, lightweight, easy-to-use, and require little to no training. Handheld Raman systems are capable of fast analysis and identification of unknowns in the field.

Laboratory Raman systems offer a higher resolution and sensitivity compared to handheld Raman systems. With the higher sensitivity of benchtop Raman systems, it is also possible to quantify substances down to low concentrations, while handheld Raman systems are often used to fulfill identification and qualification needs.

什麼是拉曼光譜儀?

拉曼光譜儀是一種用於測量瑞利散射效應 ( Rayleigh scattering effect ) 的分析儀器。瑞利散射效應是一種光與物質相互作用時所發生的散射現象。拉曼光譜儀是用於對多種材料進行無損分析和表徵的強大工具,能夠提供有關其分子組成和結構的寶貴資訊。

拉曼光譜儀由三個部分組成:雷射、光譜儀本體和採樣介面。在 Metrohm 的拉曼光譜儀中,這三個部分均由 Metrohm Spectro 自主研發和製造。

拉曼雷射具有線寬窄、體積小、功耗低以及輸出功率和激發波長極為穩定等特性。精密設計的拉曼光譜儀則以高解析度、低雜訊、體積小和功耗低為特徵。其採樣介面可實現精確、便捷、安全的採樣。Metrohm 提供多種採樣介面和配件,可實現微量分析、穿透容器進行分析,甚至在不同空間中進行資料收集等各種場景下的自動化採樣。

拉曼光譜儀的工作原理是什麼?

拉曼光譜分析儀的雷射光束通常會直接照射在樣品上,拉曼散射的光會被收集並直接導入光譜儀。光譜儀將散射光分散成不同的波長,然後由靈敏的感測器進行檢測。

由此得到的拉曼光譜代表了不同波長下散射光的強度,它提供了有關分子振動的資訊,可用於鑑定物質或研究分子間的相互作用。

拉曼光譜儀用在什麼地方?

拉曼光譜儀已成功應用於未知物質的鑑定以及已知物質的驗證或定量分析。拉曼光譜是一種非破壞性分析技術,無需樣品製備,即可實現快速安全的分析,在某些情況下,甚至可以在樣品原包裝內進行分析。

拉曼光譜的應用包括原料驗證、進料品質控管、活性藥物成分 ( APIs )、添加劑和輔料的鑑定與分析,以及非法或黑心藥品 ( 如毒品 ) 的識別。

手持式拉曼光譜儀和實驗室用拉曼光譜儀有什麼不同?

手持式拉曼光譜儀體積小、重量輕、易於使用,幾乎無需接受訓練即可使用。手持式拉曼光譜儀能夠快速分析鑑定現場未知物質。

與手持式拉曼光譜儀相比,實驗室拉曼光譜儀具有更高的解析度和靈敏度。憑藉著更高的靈敏度,桌上型拉曼光譜儀甚至可以定量分析低濃度物質,而手持式拉曼光譜儀通常用於滿足鑑定和定性需求。
