developed by Dodgson & Price (1962). Traces of sulphate groups were also investigated by infrared spectroscopy (Chopin et al. 1999). 147 Monosaccharide composition The monosaccharide composition of extracted polymers was investigated by gas chromatography (GC). 1 mL of dialyzed RPS or CPS extract, together with 20 µg of myoInositol standard were hydrolysed by addition of 1 mL of a 1 M solution of acetyl chloride in anhydrous methanol (Instant methanolic HCl; Alltech), for 24 h at 80 °C. The hydrolysates

conidia at 2h, 4h and 6h, mycelia or conidiating mycelia frozen in liquid nitrogen, crushed and then lyophilized. Dessicated samples were suspended in water (900 μl for 100 mg dry weight) and boiled 10 min. Supernatants were analysed by thin layer chromatography (TLC). 1 to 2 μl of each sample were deposited on TLC-plates SIL G-25 (Macherey-Nagel) and separated in acetonitril:ethylacetate:propanol:water, 85:20:20:15. Sugars and polyols were revealed using 0,5% KMnO 4, 1N NaOH and were identified by using

of a series of articles designed to help injection moulders understand how a few analytical tools can help diagnose a part failure problem. It deals with the techniques required to carry out a full analysis of a compound, such as gel permeation chromatography (GPC), the oxidation induction time (OIT) test, and energy-dispersive X-ray spectroscopy.
