ELECTROTHERMAL ATOMISER

摘要

An electrothermal atomizer comprises a graphite tubular member (1) which is clamped between two pairs of graphite contact members (3,5). The contact members are provided with semicircular grooves (14,22) between which the tubular member is clamped with a sufficient force to flex the wall of the tubular member to conform to the profile of the grooves. This arrangement improves the electrical contact between the tubular member (1) and the contact members (3,5) as contact over an area is provided rather than point or line contact.
