This article introduces the widespread use of fatty acid monoamides as slip agents (lubricants) in the production of polymeric films and as anti-adhesives in the food industry. The advantage of using fatty acid monoamides is their biodegradability. Unsaturated amides show better performance than saturated analogues. Some of these amides are also endogenous bioactive substances and cause sleepiness. The authors separated saturated and unsaturated fatty acid monoamides using GC-Capillary Wide Bore technique.
This document details the separation of saturated and unsaturated fatty acid monoamides, which are used as slip agents and anti-adhesives. The authors, Eric Vermeulen and Norbert Reuter from Agilent Technologies, highlight the biodegradability and performance differences between saturated and unsaturated amides.
The note specifies the analytical method used, including the CP-Sil 5 CB capillary column, helium carrier gas, and temperature program. It also provides a table identifying the four separated peaks as Oleamide, Stearamide, Erucamide, and Behenamide.
| Column | CP-Sil 5 CB, 0.53 mm x 15 m, df= 0.15 pm |
|---|---|
| Part Number | CP8673 |
| Carrier Gas | Helium at 10 mL/min |
| Temp Program | 150 °C - 6 °C/min - 200°C until end |
| Injector | 1041 Packed/Wide Bore On-Column (PWOC) Injector |
The column part number is CP8673.
The document describes the separation of four slip agents, specifically saturated and unsaturated fatty acid monoamides.
The temperature starts at 150 °C, increases at 6 °C/min, and ends at 200 °C.
Helium is used as the carrier gas at a flow rate of 10 mL/min.
