TD-50 thermal analyzer Introduction
The TD-50 has three modes of operation, namely sampling mode, resolution mode and aging mode.
Sampling mode: Available when the sampling pump is selected. The sampling mode includes five processes: online sampling, dry blowing, analysis, injection, and cleaning. At the time of sampling, the sample pump draws the sample gas into the internal line of the TD-50, and some components of the sample are adsorbed on the analytical tube. For TD-50s that are not equipped with a sampling pump, the sampling task is done offline.
Analytical mode: The analytical mode includes four processes: dry blow, analysis, injection, and cleaning. Automatic leak detection and online sampling are not included.
Automatic leak detection: Yes when EPC is selected. An automatic leak detection function will be added, which will be arranged before the first two modes, the dry blow process.
Aging mode: Aging is not a part of the sample analysis process. After running the sample for a long time or multiple times, the performance of the analytical tube may be degraded. It takes a long time of high-temperature baking to remove the water vapor and residual contaminants in the analytical tube and the instrument, so that the adsorption capacity is restored to a better state. .
Analyze & Inject: You can choose to separate or combine the parsing phase and the injecting phase by setting the injection mode. When the two are separated: In the analysis stage, the instrument will heat the adsorption tube in the case of closing the carrier gas flow in the adsorption tube. At this time, since the adsorption tube is in an approximately sealed state, the components analyzed by the heat will be filled in the cavity in the adsorption tube, waiting for the injection. The user can set the parsing time to set the time of the parsing phase. This mode effectively reduces the chromatographic peak width of light component samples, thereby increasing the sensitivity of light component analysis. When the analysis phase is combined with the injection phase, the temperature rise of the adsorption tube will start at the same time as the injection mode. The components in the sorbent tube are injected into the inlet of the chromatograph while being resolved. For target analytes with higher boiling points, this mode can be used to reduce residue.
