Applying Empore™ E3technology™ to Proteomic Sample Preparation
E3technology™ delivers equivalent or better performance than established methods (FASP, SP4, SPEED, S-tip) for proteome identification and quantitation, with high reproducibility (Pearson > 0.95) across multiple sample types and formats. Authors: Gregory Davison, Xiaohui Zhang, Guotao Lu, Cheng Tse Huang Introduction Proteomic sample preparation remains one of the most critical — and often most frustrating — steps in mass spectrometry-based proteomics. Traditional methods lik

Determination of Chlorinated Dioxins and Furans in Four Types of Wastewater by EPA Method 1613 Rev. B
CDS Empore™ C18 SPE Disks provide rapid, reliable sample preparation with excellent analyte recovery for screening and monitoring dioxins and furans in wastewater per EPA Method 1613 Rev. B. Average recovery of native compounds across four wastewater types: 109%. Authors: Guotao Lu Introduction EPA Method 1613 Rev. B was developed for isomer-specific determination of 2,3,7,8-substituted, tetra through octa-chlorinated dibenzo-p-dioxins and dibenzofurans in aqueous, solid, and

Analysis of Polynuclear Aromatic Hydrocarbons Using US EPA Quick Turnaround Method (QTM) by CDS Empore™ Disk
A simple, validated method for extracting 16 PAHs from 100 mL water samples using the CDS Empore™ C18 47mm disk, with GC-FID quantification achieving average RSDs below 6.2%. Authors: Guotao Lu Why PAH Monitoring Matters Polycyclic aromatic hydrocarbons (PAHs) are among the most hazardous organic pollutants found in the environment. This group of over 100 compounds — formed during the incomplete combustion of fuels like wood, coal, diesel, and oil — is also present in crude o
