No need for liquid nitrogen
The operation of DLaTGS (deuterated L-alanine doped glycine sulfate) detector does not require liquid nitrogen. Therefore, this system is particularly suitable for testing scenarios that require an automatic sampler or longer testing times.

No need for separate transmission lines
No separate transmission lines or any separate heating controllers are required. The outlet of the thermogravimetric instrument is directly connected to the gas chamber with built-in heating of the infrared instrument through a short heating tube. The gas connection path is short, the volume is small, and it can ensure fast response. It has irreplaceable advantages for situations where the escaping gas is prone to condensation.

TGA-FT-IR analysis of ethylene vinyl acetate (EVA)
This example is the TGA-FT-IR test of EVA samples between 25 ° C and 600 ° C. The weight loss step (TGA, black curve) of the EVA sample matches very well with the absorption peak between 600cm-1 and 4000cm-1. Two dimensional spectra related to the composition of escaping gases at any temperature can be extracted from three-dimensional spectra, and can be identified and searched in spectral libraries such as the NIST-EPA escaping gas spectral library.
The TGA curve (black), DTGA curve (black dotted line), and Gram Schmidt spectrum (blue) are shown in the following figure. The other two proposed curves (absorption intensity versus temperature curve; red and green lines) have a good correlation with the DTGA curve. The first weight loss step at 350 ° C is due to the volatilization of ethylene (red curve). In the second weight loss step, ethylene has completely evaporated. The green curve represents the change in absorption intensity of hydrocarbons released due to the decomposition of the polymer main chain (DTGA peak at 468 ° C)

Lanthanum oxide - gas evolution analysis (TGA-FT-IR)
Lanthanum oxide is mainly used in the field of catalysts, as well as in manufacturing high-quality optical glass and producing metallic lanthanum. Lanthanum oxide has hygroscopicity and is highly capable of absorbing water from the environment.
In this example, 643.4mg of lanthanum oxide sample containing a small amount of carbonate impurities is weighed and placed in a 3.5ml cup-shaped crucible, heated to 1120 ° C at a rate of 50K/min in N2 atmosphere. Nike can provide large volume crucibles, which are very suitable for samples containing small amounts of impurities or uneven samples.
The thermogravimetric curve shows multiple weight loss steps. Before 400 ° C, there was a small overlap in several weight loss steps, and the next two weight loss steps separated well, with DTG peak temperatures of 510 ° C and 705 ° C, respectively. The total weight loss of the sample at 1100 ° C is 0.43%. The infrared spectrum shows that water and carbon dioxide are the main gas products.
The figure shows that the first step of weight loss before 400 ° C is mainly dehydration, while the product of the two-step decomposition reaction between 400 ° C and 800 ° C is carbon dioxide.
Based on the above information, it can be inferred that the total water loss is 0.22% (1.41mg), and the release of CO2 is 0.21%.

Decomposition of Polyoxymethylene (POM) (TGA-FT-IR)
Polyoxymethylene (POM) is a widely used semi crystalline thermoplastic material. Due to its excellent rigidity, cutting performance, wear resistance, and dimensional stability, it is commonly used in the manufacture of precision parts.
POM decomposes into formaldehyde at high temperatures. To gain a deeper understanding of this process, a 2.92mg sample of polyoxymethylene was heated to 740 ℃ under a nitrogen atmosphere at a heating rate of 20K/min.
In the figure below, the polymer exhibits a weight loss step between 300 ℃ and 460 ℃. The maximum decomposition rate is at 414 ℃ (peak temperature on the DTG curve). On the DSC curve, the peak temperature of 171 ℃ corresponds to the melting of polyoxymethylene, which is consistent with the literature values. The other two peaks with temperatures of 389 ℃ and 414 ℃ correspond to the decomposition reaction of polyoxymethylene, respectively. The experiment shows that the temperature correspondence on the DTG, DSC, and infrared Gram Schmidt curves is very good.

Due to the Nike Proteus®The perfect combination of software and Bruker OPUS software, during the testing process, the Gram Schmidt curve obtained by integrating the entire wavelength range can be automatically recorded in the Nike test file.
The three-dimensional infrared spectrum contains the temperature coordinate (Z-axis) and TGA curve, providing another powerful evidence for the thermal decomposition analysis of the sample.

To determine the composition of the escaping gas, a two-dimensional spectrum (red) at 410 ℃ was extracted from the three-dimensional spectrum and compared with the standard spectrum in the infrared database. The comparison results showed that the gas composition was formaldehyde (green standard spectrum) and CO (blue standard spectrum).
