Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of …

2021年7月13日 · In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum.

2020年4月29日 · Spectrometer is an umbrella term that describes an instrument that separates and measures spectral components of a physical characteristic. They are devices that measure a continuous variable in which the components of the spectrum are …

Spectroscopy is the detailed analysis of a light signal by wavelength. Ordinary color images break up light into 3 channels (red, green, and blue), but spectroscopy is generally concerned with breaking up light into a higher number of bands (e.g. 10, 100, or more), and a spectrometer is the instrument that does just that.

Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.

Whether you’re detecting disease biomarkers or performing forensic analysis on drugs of abuse, our mass spectrometers give you the resolution, accuracy, sensitivity, and throughput that you need to advance your science.

2021年11月11日 · There are several kinds of spectrometers, each type with far-reaching applications and unique strengths. Mass spectrometers measure the mass-to-charge ratio and Nuclear Magnetic Resonance (NMR) spectrometers measure nuclear resonant frequencies.

Three basic elements are present: a radiation source, a monochromator, and a transducer. It is usual for the source to emit radiation of many frequencies within a region of the entire electromagnetic spectrum, for example, the IR region, the visible light region, x-rays, and so on.

Un spectrometru este un instrument folosit pentru măsurarea spectrelor. [1] Spectrometrele optice, în particular, analizează intensitatea luminii ca o funcție de lungime de undă sau de frecvență.
