42 Agilent Vapor Generation Accessory VGA 77 and VGA 77P User’s Guide
CAUTION
Bubble type collectors must not be used, because the VGA 77 is not designed to
accommodate the excessive back pressure generated by such collectors. Using
bubble type collectors may lead to vapor being forced through the drain of the
gas/liquid separator and results in an unreliable signal.
Collectors of loosely packed metal foil may be suitable if they comply with local
laws.
Connection to the Autosampler
The VGA 77 may be connected to an Agilent or compatible
autosampler for automatic sampling. Use a suitable piece of tubing to
join the sample capillary on the VGA 77 to the tubing attached to the
probe of the autosampler.
