What is the mass spectrometer of liquid chromatography?

Liquid chromatography Weight spectrometer (LC-MS) is a device used in analytical chemistry to determine the content of the sample substance. It makes two different techniques: liquid chromatography and mass spectrometry. The first of these techniques, liquid chromatography, is used to divide the sample into its chemical components. Weight spectrometry is then used to collect information about the weight of each component. The material spectrometer of the liquid can provide highly sensitive values ​​and has use in many different fields, including pharmaceutical research and forensic toxicology.

Chromatography is the first technique used by the mass spectrometer of liquid chromatography. The sample solution, which is in the liquid phase, is drained through a column containing a stationary phase substance - for example, a porous solid. Because different types of particles in the sample go through a stationary phase at different speeds, they separate into the bands.

Separation in the column can occur in many OHIce. If the molecules of one substance are larger than the other molecules, it takes longer than the porous material flows and therefore separates from smaller molecules that move faster. The flow rate can also affect chemical factors. For example, polar molecules - those that have a partial electric charge - can be attracted to the stationary phase hub and become "sticky", flows less quickly.

The weight spectrometer of liquid chromatography passes through each belt of separated material using ultraviolet light and detects its absorbance. In other words, it notes how much light and what wavelength of light the substance is absorbed. This information can often be used to identify a substance. In cases where more data is required, the particles can be further analyzed using a part of the mass spectrometer device.

particles that have been separated by the type is the phase of the chromatography liquid separated by the mass in the phaseI weight spectrometry. First, the particles are ionized or charged by removing electrons and provide them with a positive overall charge. The magnetic field is then used to "bend" the path of the charged particle when it passes through the device. The larger weight particles are not as easily movable as lighter, smaller particles, so they are not as far away. The mass spectrometer electrically records the amount of each type of particle that successfully achieves the detector.

The advantage of the mass spectrometer of liquid chromatography is that it can record, with a high sensitivity, type and weight of each chemical component of the sample. It is often used to analyze complex organic samples in pharmacological research and in the protein study. The mass spectrometer of liquid chromatography even has Been improved for use in forensic toxicology, for analysis and identification of samples that would otherwise be too fragile to study.
