Decoding Fluorine-Nitrogen Gas Production: Key Factors in Purity Control
Purity control in fluorine-nitrogen (F₂/N₂) gas production centers around five critical stages: raw material control, impurity removal, precise gas blending, system protection, and real-time monitoring. Strict control of trace impurities such as HF, moisture, oxygen, and...Read more -
Closed-Loop Feedback Control of Feeding: How Feedback Control Is Reshaping Fed-Batch Fermentation
In the world of batch fermentation, adding all the nutrients at once is like asking microorganisms to run a marathon without any additional supplies. The result is often the same: they sprint too hard in the early stage and run out of energy later on. Fed-batch fermentat...Read more -
Unstable Spectrometer Measurements? The Easily Overlooked Details (Part 2)
In the previous article, we discussed how calibration, ambient light, and probe positioning can affect spectral measurement stability. In real-world testing, however, there are several other common issues that are even easier to overlook. Although they may seem minor, th...Read more -
Research on High-Sensitivity Online Detection Technology for Multi-Component Fluorine-Containing Gases and Nitrogen Trifluoride (NF₃)
Nitrogen trifluoride (NF₃) and fluorine-containing gases such as SF₆, CF₄, and HF are widely used in the semiconductor, fluorochemical, power, and other industries. These gases are characterized by strong corrosivity, high toxicity, and greenhouse effects. Their leakage ...Read more -
Understanding the Principles of Fermentation Processes: Unveiling the “Metabolic Factory” Inside Microbial Cells
Fermentation, an ancient technique imbued with the power of modern science and technology, is fundamentally driven by the intricate metabolic processes taking place inside microbial cells. It is not simply a process of “decay” or “spoilage,” but rather a controlled and h...Read more -
Spectrometer Testing Instability? The Easily Overlooked Details (Part 1)
When using a spectrometer for transmittance, reflectance, color, or compositional analysis, many users encounter the same problem: even with the same sample and the same instrument, the measured data can fluctuate significantly, resulting in poor repeatability. The first...Read more -
Real-Time Production Control! Online Monitoring of Fluorine-Nitrogen Gas Makes a Difference!
Fluorine-nitrogen gas, with its highly reactive etching capability and high purity, is widely used in advanced manufacturing processes such as semiconductor wafer etching and precision cleaning of high-end components. The accuracy of gas composition, purity stability, an...Read more -
Key Considerations for Probe Installation: How to Avoid Interference from Bubbles and Agitator Blades?
In online monitoring of fermentation processes, traditional probes such as pH, dissolved oxygen (DO), and temperature probes, as well as emerging spectroscopic probes such as near-infrared (NIR) and Raman probes, serve as our “eyes” for sensing the physicochemical and bi...Read more -
Three Simple Ways to Improve the Signal-to-Noise Ratio (SNR) of Your Spectrometer
Have you ever struggled with large fluctuations in spectral data or weak signals being buried in noise? Signal-to-noise ratio (SNR) is a key indicator of spectrometer performance. It directly determines the quality and reliability of measurement data. The good new...Read more -

Analysis of Existing Difficulties in the Hexafluoropropylene Oxidation Process Detection
Hexafluoropropylene, as an important fluorinated olefin feedstock, is relatively chemically stable at room temperature. However, under industrial conditions such as high temperature, oxygen‑enriched atmospheres, and specific catalysis, it can undergo directed oxidation r...Read more -
Online Raman: How to Capture Astaxanthin Inside Yeast Cells in Real Time?
Phaffia rhodozyma has drawn significant attention for its ability to synthesize high-value astaxanthin. However, since this product is contained within the cells, traditional extraction and detection procedures are extremely cumbersome. The paper highlighted in this issu...Read more
