An improperly crimped vial is the most common cause of poor method performance in GC headspace analysis. The seemingly routine task of obtaining an optimal seal consistently is often poorly understood, resulting in poor precision and sensitivity. This short video shows you how to get the optimal seal every time and highlights how to avoid common errors. Taking a few minutes to watch this video could significantly improve the performance of your headspace analysis.
