Background Interference in FTIR Analysis: Sources and Effective Elimination Methods
Read moreIn FTIR Accessories, background interference has a direct impact on baseline flatness, peak shape accuracy, and the reliability of both qualitative and quantitative analysis. Uncontrolled interference can obscure weak absorption bands, distort spectral features, and compromise reproducibility, particularly in trace or high-precision measurements. To support routine laboratory operation and troubleshooting, the most common sources of […]

Five Key Factors Affecting the Resolution of Infrared Spectroscopy
Read moreThe resolution of infrared spectroscopy determines how clearly spectral peaks are separated, how accurately peak positions are identified, and how reliably overlapping signals can be analyzed. In Fourier Transform Infrared Spectroscopy (FTIR Accessories), resolution is not controlled by a single parameter but by a combination of hardware performance, optical quality, and data processing settings. The […]

What’s the reason for cracking and chipping when demolding IR tablets?
Read moreThere are always some newcomers who have just started working with Laboratory IR press who raise such questions. Today, I will share the reasons and solutions with you. The reasons can be summed up in four points. 1. Inappropriate ratio of sample to KBr This is the main reason. If the proportion of the sample […]
