Performing a TVOC Run
1. Press Enter Menu, then DISPLAY, VOC and REPORT (or GRAPH).
2. Press Start Stop.
The analysis will start and a box indicating a run on Column V (the VOC
column) will be displayed.
NOTE: If you are performing a syringe injection, make sure Explorer is configured for a
syringe injection and prepare the syringe sample before you press Start Stop. The
analysis will start and you will have 10 seconds to make the injection. A count down
timer in the status line will show the time for you to prepare for the injection. Guide
the syringe needle through the hole in the injection port until the needle point
touches the septum, but do not pierce the septum or depress the plunger. After the
beep, push the needle though the septum until the barrel comes up against the
injection port and immediately depress the plunger. Depressing the plunger must be
a rapid movement.
CAUTION
Never inject liquid or solid samples into the Explorer, you will
damage the instrument.
NOTE: The number displayed is not a real time reading. The display value will be updated
at the end of the TVOC analysis. The status line now shows a timer, a run number,
the column and detector in use. A bar showing the progression of the analysis is
also displayed. A status of “OK” is shown beside the numerical value. See Status
Line on page
59 for other possible status messages.
