Application Data from Recent Oil Spill to Help Determine the Environmental Impact
 13 Aug 2010: LECO has released a new application note highlighting the analysis of two petroleum samples obtained from the recent oil spill in the Gulf of Mexico. Using a Pegasus® 4D GCxGC-TOFMS with GERSTEL autosampler and ChromaTOF® software, the analyst was able to resolve and identify an unprecedented number of individual components in a single analysis for the ultimate in high throughput.

Sieving of Agglomerating Powders with the Air Jet Sieving Machine AS 200 Jet
11 Aug 2010: This technical note describes a method of air jet sieving for agglomerating powders. Air jet sieving is usually the method of choice for dry sieving of materials with particle sizes below 40 microns. However, it is also a faster alternative to vibratory sieving of materials of up to 250 microns.

Using the CryoMill for Samples with Volatile Components
10 Aug 2010: This technical paper discusses size reduction using a cryogenic mill for samples with volatile components. The sample is embrittled by liquid nitrogen which improves its breaking behavior when submitted to impact, pressure and friction; moreover, volatile components of the sample are preserved.

How Clean are your Vials and Closures?
13 Jul 2010: This poster from HPLC 2010 demonstrates the effectiveness of pre-cleaned National Scientific MS vials. The MS certified vials and various competitor vials were exposed to acetonitrile for two hours and subsequently analyzed by LC/UV, LC/MS and GC/MS. Resulting data showed no evidence of sample contamination using the National Scientific MS Vials.

Rapid Screening Method for PAH Samples
07 Jul 2010: Polyaromatic Hydrocarbons (PAHs) are a class of persistent organic pollutants (POPs) that are carcinogenic and mutagenic in humans. This application note represents the fastest screening method available for Polyaromatic Hydrocarbons (PAHs) using a conventional GC system. The narrow bore GC columns do not require any special hardware or modification to the GC system.
