Nettoyage des déversements

A T T E N T I O N

Risque d'exposition chimique. Mettez au rebut les substances chimiques et les déchets conformément

aux réglementations locales, régionales et nationales.

1. Respectez toutes les règles de sécurité du site concernant le contrôle des déversements.

2. Jetez les déchets en suivant les règles applicables.

Nettoyage de la vanne et de la conduite d'échantillon

A T T E N T I O N

Risque d'exposition chimique. Respectez les procédures de sécurité du laboratoire et portez tous les

équipements de protection personnelle adaptés aux produits chimiques que vous manipulez. Consultez

les fiches de données de sécurité (MSDS/SDS) à jour pour connaître les protocoles de sécurité

applicables.

Les tubes, vannes et autres équipements de conditionnement d'échantillon neufs peuvent être

contaminés par des substances à base de silice (huiles, poussière). S'ils ne sont pas nettoyés, les

mesures risquent d'être légèrement trop élevées.

1. Rincez la conduite d'échantillon avec l'échantillon pendant une à deux heures.

2. Pour un nettoyage efficace, injectez un à quatre litres de solution caustique diluée, comme une

solution d'hydroxyde de sodium 1N (5 %) à l'extrémité avant de la conduite d'échantillon. Faites

passer la solution à travers l'analyseur pour nettoyer les composants du système

d'échantillonnage.
