|
|
|
None of the above

Explanation:
Detailed explanation-1: -HPLC cannot be used to determine mercury content in fish because it is used to separate similar molecules, hence, mercury content in fish is determined by atomic absorption spectroscopy.
Detailed explanation-2: -Explanation: Except capillary columns, all other columns are used in high performance liquid chromatography. In gas chromatography, a capillary column is used.
Detailed explanation-3: -High-performance liquid chromatography (HPLC) machines push substances through using a high-pressure pump. These machines help forensic scientists analyze volatile substances such as gunpowder residue, fibers, and toxins. One of its most common uses is to determine materials used in explosives.
