Spme hplc interface

Manufactured by Merck Group

Sourced in United States

The SPME-HPLC interface is a device that connects a Solid Phase Microextraction (SPME) system to a High-Performance Liquid Chromatography (HPLC) instrument. The core function of this interface is to facilitate the transfer of analytes extracted by the SPME fiber into the HPLC system for separation and detection.

Example 1

A 50 ng/mL solution of the internal standards containing EMPA, IMPA, PMPA, CMPA, MMPA was prepared in HPLC grade water. Four SPME fibers were evaluated for selectivity with the internal sample solution. The fibers evaluated were 100 μm PDMS, 60 μm PDMS/DVB, 50 μm CW/TPR, and 85 μm PA. Each fiber was given a 5 minute adsorption time in 3 mL of the internal standard solution, followed immediately by dynamic injection (desorption into the flowing stream of mobile phase) using a Supelco® SPME/HPLC interface. Peaks were observed in accordance with all of the IS transitions and retention times. The CW/TPR fiber provided the most intense response, followed by the PDMS, the PDMS/DVB, and finally the PA fiber. The CW/TPR fiber also provided the most balanced response for all the acids investigated. The PDMS fiber provided peak area responses that were skewed towards the earlier eluting, more hydrophobic side-chained acids (PMPA, MMPA, and CMPA) suggesting that they exhibited greater partitioning into the hydrophobic PDMS phase. The PDMS/DVB response was similar to the PDMS but slightly less intense, and the PA fiber response was low.

Anodization of Ti wires was performed with a precise WY-3D power supply (Nanjing, China). TiO₂ nanoparticles were annealed in air atmosphere at different temperatures in OTF-1200X tubular furnace with a Prog/Controller (Kejing, Hefei, China). The fabricated fibers were characterized by an Ultra Plus microscope (Zeiss, Oberkochen, Germany) with an Aztec-X-80 energy dispersive X-ray spectrometer (Oxford, UK). SPME was carried out in a DF-101S thermostat with controlled temperature and magnetic stirring (Changcheng, Zhengzhou, China). The analyses were carried out on a Waters 600E multi-solvent delivery system (Milford, MA, USA) equipped with a Waters 2487 dual λ absorbance detector and a Zorbax Eclipse Plus C 18 column (150 mm × 4.6 mm, 5 μm, Agilent, USA). Chromatographic data was processed with a N2000 workstation (Zhejiang University, China). Desorption was performed in a commercially available SPME-HPLC interface (Supelco, PA, USA). Ultrapure water was obtained from a Sudreli SDLA-B-X water purification system (Chongqing, China).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
