SPME vs. TF-SPME: Comparing Extraction Capacity, Analyte Response, and Compound Coverage
For the past few decades, as analytical labs have looked to reduce their environmental impact, solvent-free extraction techniques have gained popularity. One of the most well-known techniques is solid phase microextraction (SPME), pioneered in the early 1990s. SPME SPME consists of a coated fiber in a syringe-like holder, which extracts and enriches volatile and semi-volatile […]
Beyond PDMS: How New Twister® Sorbent Phases Expand Analyte Coverage in SBSE Workflows
Stir Bar Sorptive Extraction (SBSE) For over 25 years, stir bar sorptive extraction (SBSE) has offered analytical scientists a robust, solvent-free extraction technique for a variety of applications, from beverage profiling to extractables and leachables testing. SBSE enriches analytes from liquid and solid samples in immersive and headspace extractions. Due to its large sorptive phase […]
Choosing the Right Extraction Technique for Sensory Profiling: Direct Contact TF-SPME, Twister®/TF-SPME, and Dynamic Headspace (DHS)
The Role of Extraction Sensory profiling of products in the fragrance, flavor, and food and beverage (FFF/B) markets is imperative for understanding the consumer experience. Sensory profiles provide valuable information about compounds that influence product quality, human perception, consistency, and even authenticity. Because the extraction step determines which compounds are introduced and detected, selecting the […]
Automated Internal Standard Addition⁺ (ISDP⁺) with SBSE in TD-GC-MS for Improved Precision in Flavor Compound Determination
Introduction The dietary supplements market is valued at over 150 billion dollars (U.S.) worldwide. Dietary supplements are manufactured products that come in many forms, such as pills, capsules, powders, liquids, or tablets. They are used to supplement a person’s diet. The nutrients can be synthetic or extracted from natural sources. Many of these products contain […]
Product Integrity Matters: Improving Foods & Beverages with GERSTEL Solutions
Chemistry Drives Flavor in Foods and Beverages Consider what your favorite food or beverage may be… now ask yourself, “Why is it that I love it so much?” Aside from the price, sustainable ingredients, and nutrition facts, flavor is a top driver for consumers. Flavor is driven by chemistry, which makes analyzing the complex interplay […]
