| Environmental Response Laboratory Network (ERLN)
Tuesday, July 13, 2010Weck Laboratories joins the Environmental Response Laboratory Network. The ERLN is EPA's national network of laboratories that can be accessed as needed to support large scale environmental responses. With the threat of a chemical, biological, and radiological attack to the United States becoming more complex, the need for accurate, timely environmental testing capabilities becomes even more crucial to manage a response effectively.

| New Triple Quadrupole GC/MS Offers Greater Precision, Selectivity and Sensitivity
Tuesday, July 13, 2010 Weck Laboratories acquires Agilent Technologies new 7000B Triple Quadrupole Gas Chromatograph/Mass Spectrometer (GC/MS/MS), delivering high confidence in ultra-trace level results, while shortening analysis times for target compounds in complex samples. The 7000B provides femtogram-level sensitivity for analyses such as pesticides, PAHs, PCBs, pyrethroids, THC, and steroids in food, environmental, pharmaceutical, and forensic matrices. Advanced GC and MS/MS technologies translate into everyday high performance. MS/MS techniques are most often cited for consistent, ultra-low detection limits with very complex sample matrices. Multi-target screening methods-pesticide residues in foods, drugs in biological fluids and environmental contaminants in soil and water-have dominated much of the literature. But what's often overlooked is that any SIM method can benefit from MS/MS, with better qualitative and quantitative results. Benefits include:
- Elimination of chemical and neutral noise in the spectral region of the product ions-translating into lower detection limits than SIM
- Higher probability of a more unique (more selective) product ion-translating into fewer false negatives and false positives than SIM

| Expanded Target List and Lower Dectection Levels for Pyrethroid Pesticides
Tuesday, July 13, 2010Recent improvements in the GCMS-NCI-SIM analysis for Pyrethroid pesticides method at Weck Laboratories now includes Esfenvalerate being added to the target compound list. The enhancements also result in lowered reporting limits for most compounds from 10 ng/L to 2 ng/L. Method details here... |
| Gel Permeation Chromatograph Increases Productivity & Lowers Detection Limits in Complex Matrices
Tuesday, July 13, 2010 Weck Laboratories acquires Pickering Lab's GPC ULTRA. The ULTRA automates Gel Permeation Chromatography (GPC) sample concentration for the clean-up of complex animal tissues, food products, and environmental samples. The high recoveries and concentrated samples are easily analyzed by GC, GC-MS, HPLC or LC-MS. GPC is a well-known technology for the removal of fats, proteins, and other large bio-molecules from samples in order to prevent interference in the analysis of chlorinated hydrocarbon pesticides, PCBs, antibiotics, mycotoxins, polyaromatic hydrocarbons (PAH), and other semi-volatile compounds. Ideally suited for high-throughput laboratories requiring reliability and reproducibility, the GPC ULTRA is optimized for unattended operation, low maintenance, and consistent recoveries.
