Other Hazards
There is danger of crushing to fingers and hands. To avoid injury keep your hands away from
moving parts during operation.
Turn off the power to the TriPlus 300 Headspace sampling system if you must reach inside a
mechanically powered system with moving parts.
To avoid injury, observe safe laboratory practice when handling solvents, changing tubing, or
operating the TriPlus 300 Headspace sampling system. Know the physical and chemical
properties of the solvents you use.
See the MSDS (Material Safety Data Sheets) from the manufacturer of the solvents being
used.
When using the TriPlus 300 Headspace sampling system, follow the generally accepted
procedures for quality control and method development.
When using the TriPlus 300 Headspace sampling system in the field of chromatographic
analysis, if a change is observed in the retention time of a particular compound, in the
resolution between two compounds, or in the peak shape, immediately determine the reasons
for the changes. Do not rely on the separation results until you determine the cause of a
change.
Do not operate on the instrument components that form part of the work area of the TriPlus
300 Headspace sampling system when it is in motion.
Do not use vials without a sealing cap. Vapor phase from organic solvents can be hazardous
and flammable. Acidic vapor phase can cause corrosion to critical mechanical parts.
When sample vials have to undergo heating and agitation, it is important to consider the glass
quality. Use high quality glass only. Remember that depending on the application conditions,
high pressure can build up in the vial. Whenever a temperature greater than 60 °C is applied,
consider the vapor pressure of the solvent used to ensure that no excessive pressure builds up.
This is important when using temperatures above 100°C and especially at the maximum
temperature of 300 °C. Be aware that solid materials can also contain volatile compounds
such as water (humidity) that may cause build-up of excess vapor pressure.
Do not reuse headspace vials. During the process of washing the vial, micro-cracks can form
which will weaken the glass wall and increase the chances of the vial breaking.
