Carbon Nanotubes in SPE
Researchers from the New Jersey Institute of Technology (Newark, New Jersey) prepared a micro solid-phase extraction (SPE) device consisting of carbon nanotubes packed in the needle of a syringe.
Researchers from the New Jersey Institute of Technology (Newark, New Jersey) prepared a micro solid-phase extraction (SPE) device consisting of carbon nanotubes packed in the needle of a syringe. They used the device for sampling, analyte enrichment, and sample introduction and used both single- and multiwalled carbon nanotubes as sorbents. The needle held approximately 300 µg of the carbon nanotube sorbent. They found the packed carbon nanotube beds to provide extraction efficiencies as high as 27% and enrichment factors of close to 7. They reported that the method was linear, reproducible, and achieved low method detection limits of 0.1–3 ng/mL for MWNTs.
Gulf Coast Conference: Increasing Density and Viscosity Throughput with Difficult Samples
October 19th 2023Daniel Wolbrecht, senior technical sales consultant at Anton Paar, held a workshop at the Gulf Coast Conference in Galveston, Texas, focusing on how heated autosampler units can help analyze difficult samples.
