Aflatoxins, a mold largely produced by Aspergillus flavus and Aspergillus parasiticus1 are commonly tested mycotoxins found naturally in a wide range of agriculture crops and food products. Due to their harmful effects on human health, animal health, and global trade, aflatoxins are regulated in most countries and have established global limits in a wide variety of matrices.

This poster describes a reduced workflow solid phase extraction method for extraction of vitamin B7 (biotin) from human serum. Using EVOLUTE EXPRESS AX 96-well plates, the traditional sorbent conditioning and equilibration steps are not required, meaning the sample can be applied directly to the dry plate. Post extraction evaporation is also eliminated. ASMS 2014

This report details a “load, wash, elute” weak cation exchange solid phase extraction procedure amenable to both plasma and urine samples. The extracts are subsequently injected into an LC-MS/MS system. The preliminary sample preparation method was developed at the Biotage US Applications lab (Charlotte, NC).The method was then transferred to Ionics (Bolton, ON, Canada) to facilitate the nmole/L measurements of the selected biomarkers by laminar flow tandem mass spectrometry. The SPE-LC-ESIMS/ MS method parameters were first optimized using pooled mixed gender plasma. A set of patient samples (n=32) was later supplied by the Mayo Clinic (Rochester, MN) that had previously been analyzed by a validated referee method. The population represented measured values across a range of clinical relevance. AACC 2014

The compound 4-methylimidazole (4-MEI) is formed as a byproduct in some foods and beverages. Caramel coloring Type III and Type IV in beverages is one of the ingredients which may contain 4-MEI. Products that potentially contain 4-MEI include certain colas, beers, soy sauces, breads, coffee, ammoniated livestock feed and other products.

The compound 4 Methylimidazole (4-MeI) is made during the production of caramel color commonly found in foods and beverages, especially sodas. The Codex Alimentarius of the World Health Organization sets a limit of 250 mg/kg of 4-MeI. Also, the state of California has added 4-MeI to its Prop 65 list at an exposure level of 29 μg/day. This study looks at 4-MeI levels in sodas and malt sodas which are sold in and outside the state of California. The first section, included in this poster, describes the performance of automated solid phase extraction of 4-MeI using conventional HPLC/MS detection. ASMS 2018, San Diego, CA

The newly released Biotage® Selekt flash chromatography instrument can be run at a maximum flowrate of 300 mL/min or a maximum pressure of 30 bar. These high flowrates and pressures enable a user to perform chromatography using not only dry-packed, single-use plastic flash columns containing small (≥20 μm) spherical silica particles, but also semi-preparative, slurry-packed HPLC columns for multiple use with smaller (≤20 μm) spherical silica particles.

The DryDisk® Separation Membrane was designed to replace conventional sodium sulfate in the drying of sample extracts. The DryDisk® is a hydrophobic membrane, consisting of a GORETEX ® process filtration media based on polytetrafluroethylene (PTFE). The hydrophobic property of the membrane allows the extracting solvent to pass through it, while retaining any water in the sample extract on the membrane’s surface.

Mycotoxin testing awareness has increased as countries involved in world trade of raw agriculture and processed consumer products rely on a safe global food supply. Several mycotoxins are naturally produced and monitored; however, aflatoxins, produced mainly by the Aspergillus species, are considered to be the most important mycotoxin group in the world’s food supply to monitor.

When it comes to polar organic compound purification, many chemists turn to normal-phase flash chromatography often utilizing dichloromethane and methanol as the eluting solvents. While this can work, it often can be challenging to optimize due to methanol’s high polarity and protic chemistry.

Peptide purification via flash chromatography has recently been demonstrated as a viable alternative to the more standard HPLC methods currently utilized. Flash chromatography offers peptide chemists the advantage of significantly greater loading capacity reducing the overall purification time but with a compromise of decreased peak resolution. Herein we present several strategies that, when implemented, allow for very high purity peptide samples purified by flash chromatography.

White Papers

The use of LC/MS analysis in the clinical lab has increased exponentially over the last 10 years. Modern mass spectrometers are extremely sensitive allowing low level detection of many target analytes. However, this sensitivity can come at a price, in that levels of contamination not previously detected with less sensitive instruments can now have larger impact on analysis. The complexity of common matrices such as plasma/serum and urine while presenting different challenges can have a marked influence on method performance. As a result sample preparation is an extremely important part of the process in order to provide robust methods. This seminar focuses on some of the method development challenges our lab faced when looking at two clinical assays: Endogenous steroid hormone extraction from serum, and catecholamine extraction from plasma and urine. Particular emphasis is placed on the various sample preparation options we looked at for the extraction of these analytes. During optimization of the extraction process we investigated analyte recovery, co-extractable matrix components, HPLC column degradation, calibration curve performance and limits of quantitation.
