This technique allows forensic scientists to dissect samples at a molecular level, revealing the hidden secrets of drugs and poisons that could otherwise go unnoticed.

The process of mass spectrometry involves ionizing chemical compounds to generate charged molecules or molecule fragments and measuring their mass-to-charge ratios. This is akin to having a highly sophisticated scale that not only weighs but also categorizes the items on it. The resulting data is then used to create a spectrum that acts as a unique fingerprint for each substance, enabling forensic experts to identify and quantify the components present in a sample.

One of the most significant advantages of mass spectrometry is its ability to analyze complex biological matrices, such as blood, urine, or tissue samples. These matrices can contain a myriad of substances, making traditional analysis methods less effective. However, with mass spectrometry, scientists can separate and identify multiple substances in a single analysis, saving both time and resources. This capability is crucial, especially in cases where a victim may have been exposed to multiple drugs or toxins.

Additionally, mass spectrometry techniques can be categorized into various types, including:
