A rapid and automated degradation study of rubber under ultraviolet (UV) light in air. 6200 6000 Pyroprobe Pyrolysis Photoprobe UV Degradation

This application note establishes a rapid analysis method for Strontiumin in water in emergency situations. The 1.00 L water sample was acidified and filtered with Empore Strontium solid-phase extraction disk, and then measured Strontium levels on the extraction disk with a low-background α/β counter. The method is simple to operate with stable chemical recovery rates. The lower detection limit of the method is 0.019 Bq/L under typical conditions, and the whole experimental process takes about 2 hours, which is suitable for the rapid determination of Strontiumin in water in emergency situations.

The analytical performance of the CDS 8500 Series Purge and Trap is demonstrated for the electronic pressure control, used for internal standard delivery, to prepare calibration curves. 8500 P&T Purge & Trap Environmental

The application note developed a new EPA 8270E method by using CDS Empore 8270 disk to maximizes the advantages of the membrane solid-phase extraction technology, which include easy to stack and apply, easy reverse elution, and relatively shorter drying time, etc. The method quantitatively extract a wide range of compounds with most compounds having recovery rates higher than 75%, and the RSDs less than 15%. This method provides a very versatile option for wastewater detection. Empore Environmental

The analytical performance of the CDS 8500 Series Purge and Trap is demonstrated for the sample syringe to prepare calibration curves by performing automated sample dilution. 8500 Purge & Trap Environmental

The Empore™ StageTips product was developed utilizing the Empore™ membrane solid phase extraction (SPE) product to address the need for rapid, offline purification and desalting of peptides in proteomics sample preparation. The structures of SPE reversed phase sorbents is a critical factor to affect the Empore™ StageTips on the types and quantities of peptides extracted. In this application note, 3 types of C18 SPE sorbents and a polymeric reverse phase (Empore™ SDB-XC) have been evaluated on their effects of the corresponding StageTips on total number of protein and peptide Identifications at 4 different sample loading amounts from 10ng to 200ng in proteomics.

This application note introduces a sample-stacking technique to improve sensitivity for low concentration samples. 6000 6200 Pyroprobe Pyrolysis General Interest Environmental

This application note presents data on a rapid, automated polymer degradation study of polymers containing UV stabilizers under ultraviolet (UV) light in a temperature controlled environment.

The analytical performance of the CDS 8500 Series Purge and Trap is demonstrated for the EPA Method 8260D by GC/MS analysis.

This application note demonstrates a method for sampling and analyzing volatile organic compound (VOC) emissions of essential oils using thermal desorption (TD) GC-MS. As part of this work, VOC emissions from three different types of grapefruit essential oil were examined. Limonene, which is known to be the primary VOC emitted from grapefruit and other citrus plants, was directly quantified from emissions of in-home diffusers. For this work, limonene concentrations as high as 27 ppbv were found near the outlet of the diffuser. TD-GC-MS analysis was supplemented with headspace sampling GC-MS to further probe essential oil chemical composition. The results provide greater context into the ways in which consumer products influence indoor air quality and human health.
