Ultra high-speed separation of food additives in soft drink using X-LC with 4λ-UV detector

Food additives are substances added to food as preservatives, antioxidants, emulsifiers, etc. Recent increases in consumption of processed foods has led to the introduction more additives. Securing food safety demands determination of these additives and high performance liquid chromatography (HPLC) has been used for the measurement of these food additives.

Jasco examined the usefulness of an X-PressPak V-C (2.0 mm I.D. x 50 mm L.) packed with a 2 um diameter packing material for the ultra high-speed separation of food additives. Jasco used a 4λ−UV detector for the simultaneous monitoring of these additives at four different wavelengths. The results were examined to determine whether the performance of the column and chromatography system exceeds those of conventional HPLC.
