Hettich ROTOFIX 32 Benchtop Centrifuge Employed for HS-SPME & GC Fenthion Determination in Human Serum
The Hettich ROTOFIX 32, a multifunctional benchtop centrifuge, was used for blood sample processing in the study entitled “Headspace Solid Phase Micro Extraction Gas Chromatographic Determination of Fenthion in Human Serum.”
In the study, scientists sought to determine the most efficient method to identify fenthion in human serum. Fenthion is an organophosphorus insecticide widely used on olive fruit for protection against the pest Dacusoleae – a species of fruit fly most prevalent in the Mediterranean region. The Hettich ROTOFIX 32 was used to centrifuge blood samples at 3,500 rpm for five minutes to prepare serum for later testing.
After performing gas chromatography-mass spectroscopy (GC-MS) analysis and headspace solid phase micro extraction (HS-SPME), the scientists found that HS-SPME proved ideal for fenthion and metabolite identification in human biological samples.
Previously developed procedures for organophosphoros insecticide residue detection in olive oils utilized different cleanup techniques and laborious sample preparations such as liquid-liquid extraction (LLE) and solid phase (SPE) extraction. The simpler and more economical HS-SPME method is free from any organic solvent and maximizes the adsorption efficiency. The researchers are optimistic about the potential of this innovative procedure to determine other organophosphoros insecticides in its class.
Hettich’s comprehensive line of centrifuges enables scientists to conduct important testing and research, such as this study on the most efficient methods to identify fenthion in human serum. The Hettich ROTOFIX 32 is a robust and versatile benchtop centrifuge ideal for many clinical and research applications.
