Thermal analyzerBy optimizing the parsing process, integrating pre-processing functions, and improving automation, the complex multi-step operations in traditional sample pre-processing are compressed into continuous operation on a single device, significantly reducing overall time consumption. Its core is to reduce the sample transfer process and accelerate the separation and enrichment of target components through technical means.

1、 Process optimization: Reduce transfer steps and achieve "one-step parsing"

1. Direct injection design

Traditional pretreatment requires transferring samples (such as adsorption tubes and solid samples) to the analytical device first, and then to the detection instrument, which is cumbersome and prone to losses. The thermal analyzer supports the integration of "adsorption tube analysis injection". The adsorption tube can be directly loaded into the instrument, and the analyzed target components can be directly introduced into gas chromatography (GC) and other detection equipment through a dedicated pipeline, saving sample transfer time and shortening the single sample processing process from more than 30 minutes to 10-15 minutes.

2. Shorten the analysis and cold trap focusing time

By using an efficient heating module, the analysis temperature can be accurately controlled (up to 400 ℃) and rapid heating can be achieved (heating rate can reach 50 ℃/min), accelerating the desorption of target components in the adsorption tube and compressing the analysis time from the traditional 10-15 minutes to 2-5 minutes. At the same time, with efficient cold traps (such as electronic refrigeration cold traps), rapid focusing of target components can be achieved within 1 minute, avoiding component diffusion and eliminating the need to wait for the cold trap to cool down or heat up for a long time.

2、 Integrated design: Merge pre-processing steps to reduce device switching

1. Built in sample purification function

For example, a small column of adsorbent is built into the analysis pipeline, which can synchronously remove impurities such as water and oil from the sample without the need for additional dehydrating agents or purification equipment, eliminating the need for separate sample purification steps and saving 10-20 minutes of pretreatment time.

2. Multi channel parallel processing

The model supports multi-channel design (such as 4-channel, 8-channel) and can simultaneously analyze and process multiple samples. Traditional single channel devices can only process one sample at a time, while multi-channel devices can process 4-8 samples in one hour. In batch sample processing scenarios, the overall pre-processing efficiency is improved several times.

3、 Automated control: reduce manual intervention and avoid operational delays

1. Full process automatic control

Through the accompanying software, the analysis temperature, time, cold trap focusing parameters, injection time and other processes can be preset. After startup, the equipment automatically completes the entire process of "heating analysis cold trap focusing thermal desorption injection" without manual adjustment. In traditional pre-processing, manual operations such as temperature adjustment and pipeline switching can account for up to 50% of the time, and automation can save this time.

2. Automatic cleaning and status monitoring

The device is equipped with an automatic cleaning function. After each sample analysis is completed, it can automatically blow the pipeline and cold trap with inert gas (such as nitrogen) to avoid cross contamination, without the need for manual disassembly and cleaning. At the same time, the system monitors and analyzes key parameters such as temperature and gas flow rate in real time, and immediately alarms in case of abnormalities, avoiding repeated processing caused by parameter deviations and reducing ineffective time consumption.

The thermal analyzer adopts a combination strategy of "process simplification+functional integration+automation" to shorten the sample pretreatment time by more than 60%, especially suitable for the rapid detection needs of volatile organic compounds (VOCs) and other samples. If necessary, I can help you organize a comparison table of pre-treatment time for different types of samples (such as air, solid matrix) before thermal analysis, clearly listing the differences between traditional methods andThermal analyzerDifferences in time consumption and key parameter settings.
