The Analysis of Copper, Iron, and Manganese in Wine with FAST Flame Atomic Absorption

This work demonstrates the ability of the PinAAcle 900 flame AA spectrometer to measure Cu, Fe, and Mn in wines to comply with Chinese wine import regulations coupled with FAST Flame sample automation for increased throughput.

"No Dilute” Just Shoot: Robustness of a QSight LC-ESI-MS/MS for Pesticide Residue Analysis in Wine

QSight LC/MS/MS evaluates eliminating sample preparation for trace level pesticide in wine

Analysis of Ethyl Carbamate Using GCMS

Ethyl carbamate is a naturally occurring ester formed in fermented foodstuffs such as bread and in beverages such as wine. The agencies also suggest steps to minimize formation of ethyl carbamate, such as minimizing exposure to heat and light and limiting storage time of finished product. The method selected for this work is the AOAC International 944.07 method for Gas Chromatography and Mass Spectrometry detection (GC/MS). The method calls for calibration of ethyl carbamate with a propyl carbamate internal standard. As part of this experiment, butyl carbamate was investigated as an alternative internal standard.

Direct Analysis of Glyphosate in Wine with No Sample Preparation

Glyphosate is an organophosphate herbicide that is used on crops to kill weeds and grasses. We present a study that involves direct analysis of glyphosate in wine on a mixed mode column with no sample dilution or extraction using a PerkinElmer QSight® 220 triple quadruple mass spectrometer with a patented StayClean™ source, consisting of a hot surface induced desolvation (HSID)™ interface and a Laminar Flow Ion Guide™. Both the HSID and ion guide prevent any contaminants from entering the mass spectrometer, keeping it at its highest performance level and, thereby, maintenance free.

Pesticide Residues and Illegal Additives in Wine

Both pesticides and illegal additives, if present in significant levels in wine, can pose health risk to consumers. In this study, a simple and sensitive LC-MS/MS method has been developed and applied for the determination of both pesticides and pigments in a single analytical run.

Pesticide in Grapes by LC-MS/MS

The Grape crop is one of the most important fruit crops consumed in the world. Grapes are consumed both as fresh and as processed products, such as wine, jam, juice, jelly, grape seed extract, raisins, vinegar and grape seed oil. A large variety of pesticides are used in grape production throughout its growing season to control pests and diseases in vineyards and to increase crop yield. Pesticide residue is a major concern for the stakeholders of the grape industry, due to more and more stringent regulations and safety standards in most countries.

Qualitative Evaluation of Aroma-Active Compounds in Grape and Grape-Derived Products by Means of Headspace SPME-GC/MS Analysis

Grapes are probably the first cultivated fruit: its domestication by man began 6000-8000 years ago across the area between the Caspian and Black Seas and over the centurie.

Determination of Wine Color and Total Phenol Content using the LAMBDA PDA UV/Vis Spectrophotometers

This application note shows the versatility of PerkinElmer’s LAMBDA™ 265 and LAMBDA 465 PDA UV/Visible Spectrophotometers for quantification of the total phenol content in the wines, and also wine color to be measured to determine quality and any potential contamination.

Geographical Differences of Trace Elements in Wines – Analysis with NexION 300X/350X ICP-MS

In this study, a total of 75 Italian red wines from different regions and grape types were analyzed by ICP-MS to determine whether elemental profiles correlate to the region of origin. Results were imported into TIBCO Spotfire® software for statistical calculations and to display geospatial distribution.
