Learn how to prepare your sample for analysis by GC-MS, and select the correct GC column for your sample.

The frequency of the FID maintenance is dependent upon the sample matrix and application your laboratory is conducting. Read this technical note to learn how to correctly maintain your flame ionization detector (FID).

Achieving consistent, reliable results begins with robust quality control. In this technical note, SCION Instruments outlines practical QC best practices and calibration strategies to help laboratories ensure accuracy, compliance, and confidence in their analytical data.

Samples that are to be analysed by GC-MS often contain dirty compounds that sometimes require ‘specialist’ sample preparation as detailed in this guide.

Analyte confirmation can be specified as a requirement for method validation to ensure that compounds during the analysis have been correctly identified. This can be important across many industries to ensure active ingredient(s) and/ or impurities within a sample can be validated as the purity or identity they have been described as for both safety and quality control.

Solid phase extraction (SPE) is a powerful sample preparation technique used across many different industries including pharmaceutical, environmental and forensics. The main aims of sample preparation is to remove or minimise sample matrix effects.

Mass spectrometry analysis requires an internal standard (IS) to ensure accurate quantitation and to correct for various sources of variability that can affect the results. 

Biodiesel analysis is essential for ensuring fuel quality, engine performance, environmental compliance, and consumer safety. Proper testing identifies impurities, enhances fuel efficiency, and helps prevent engine damage.  

Soil composition directly affects the quality and usability of soil which is why analyzing substances within soil demands precise methods. Soil pollution arises from both natural and human activities, including volcanic eruptions, soil erosion, continental dust, and urban runoff.

Selecting the right column depends on several key factors, including your application market, base material, functional group, and separation mode. Therefore, understanding these elements is essential for achieving the best analytical results.
