Sample Injection

Sample injection is a technique used in scientific analysis, especially in laboratories, where a small amount of a sample is introduced into a measurement instrument, like a chromatograph or spectrometer. This process ensures that the sample is accurately and precisely fed into the device for testing. By controlling the injection volume and speed, scientists can obtain reliable data about the sample’s composition. It is a critical step in analytical procedures, allowing for consistent, repeatable measurements with minimal sample consumption.
