This test method is used for analyzing ionic contaminants (anions) in ethanol using ion chromatography (IC). This test is important for assessing the purity and quality of ethanol, especially fuel-grade ethanol, where ionic impurities can affect performance and stability. This test method can quantify chloride, phosphate (ortho as P), sulfate, and potential sulfate.
This test method uses static headspace gas chromatography with flame ionization detection (GC–FID) to measure fusel alcohols—higher-chain alcohols produced during fermentation. The measurement of fusel alcohols is important for quality control, regulatory compliance, and detecting potential adulteration or off-spec fermentation. This test method identifies isopropanol, N-propanol, isobutanol, isoamyl alcohol, and N-amyl alcohol.
The FCC (Food Chemicals Codex) method for Acidity as Acetic Acid in Ethanol is a titrimetric procedure used to quantify the free acidity in ethanol by expressing it as an equivalent amount of acetic acid. This test helps assess the purity and quality of ethanol, especially in food, pharmaceutical, and beverage applications. The inclusion of… Continue reading FCC Acidity as Acetic Acid in Ethanol with N Sparge
The FCC (Food Chemicals Codex) method for Alkalinity (as NH₃) in Ethanol is a titration-based analytical procedure used to determine the basic impurities in ethanol by expressing the result as an equivalent amount of ammonia (NH₃). This test helps ensure ethanol meets purity specifications for food, beverage, and pharmaceutical use.
The FCC (Food Chemicals Codex) Metals Analysis for Ethanol is a group of analytical procedures designed to detect and quantify trace metal impurities in ethanol intended for food, beverage, and pharmaceutical use. These methods ensure ethanol purity and compliance with safety standards by targeting toxic and residual metals. This test method quantifies boron, calcium, copper,… Continue reading FCC Metals [Ethanol]
The FCC (Food Chemicals Codex) method for Nonvolatile Residue in Ethanol measures the amount of residual, non-evaporative material left behind after ethanol is evaporated under controlled conditions. This test helps determine the presence of impurities such as sugars, salts, or other nonvolatile contaminants, which may affect the purity, taste, or suitability of ethanol for food,… Continue reading FCC Nonvolatile Residue in Ethanol
The FCC method for Organic Impurities in Ethanol is designed to detect the presence of organic contaminants (e.g., fusel oils, ketones, methanol) in food-grade or pharmaceutical-grade ethanol. These impurities can affect the taste, odor, and safety of ethanol used in consumable or medicinal products.
