Which type of gloves is typically used in n-hexane analysis?

Nitrile gloves are typically used in n-hexane analysis due to their excellent chemical resistance properties. N-hexane is an organic solvent that can easily permeate through materials that are less resistant, such as latex and vinyl. Nitrile, on the other hand, provides a barrier against organic solvents and is less likely to degrade when in contact with them. This makes nitrile gloves a safer and more reliable choice for handling n-hexane, protecting the analyst from potential skin exposure and ensuring the integrity of the sample being analyzed.

Latex gloves can be unsuitable because they may not provide adequate chemical resistance against solvents like n-hexane and can be prone to wearing down quickly when exposed to such chemicals. Vinyl gloves do not offer the same level of chemical protection as nitrile gloves, making them less effective for tasks involving potent solvents. Leather gloves, while durable and protective against physical hazards, are not appropriate for chemical analysis, especially when dealing with organic solvents like n-hexane that can damage or permeate through the leather.
