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 -
Top 10 Common Questions for Spectrometer Selection (Part 2)
When building a spectral detection system or selecting a spectrometer—whether you are a researcher, engineer, or system integrator—you will inevitably face a series of selection challenges. In the previous article, we discussed five core selection issues: spectral...Read more -
Online Raman Spectroscopy Empowers Process Optimization and Quality Control of Hexafluoropropylene
As a core pillar of the advanced new materials industry, hexafluoropropylene (HFP) serves as a key fluorinated monomer. Its purity and production stability directly determine the quality ceiling of downstream fluoropolymers, electronic chemicals, and other products. In t...Read more -
The Mystery of Nitrogen Metabolism: The Relationship Between Online Monitoring of Ammonium Ion and Amino Nitrogen and Protein Synthesis and Product Secretion
If carbon sources are the "fuel" driving the cell factory, then nitrogen sources are the "bricks and mortar" building the life machine itself. Nitrogen metabolism not only concerns bacterial growth but also profoundly influences the direction of metabolic pathways and th...Read more -
Top 10 Common Questions for Spectrometer Selection (Part 1)
When building a spectral detection system or selecting a spectrometer, researchers, engineers, and system integrators alike face a series of selection challenges. To help you get started quickly, we have compiled the ten most common questions in spectrometer selection ba...Read more -
Analysis of the Difficulties in Detecting Hexafluoropropylene Oxide Isomers
Hexafluoropropylene oxide (HFPO) is a key monomer used in the synthesis of perfluoropolyethers and fluorosurfactants. During its synthesis, hexafluoroacetone (HFA, C₃F₆O) and pentafluoropropionyl fluoride (PFPF, C₃F₅O) are often generated as by-products. Among these, HFA...Read more -
The “Invisible” Substrate Flow: How Does Online Monitoring Reveal the Consumption Trajectory of Carbon Sources (e.g., Glucose)?
Within the fermentation tank—this "black box"—the consumption of carbon sources (such as glucose) is the core driving force behind all life activities and product synthesis. However, traditional offline detection methods—periodic sampling and residual sugar analysis—can ...Read more -
The Heart of the Spectrometer: Reflection Gratings vs. Transmission Gratings — How to Choose
At the core of the spectrometer—the "light decoder"—lies a critical component that determines its performance: the grating. It serves as the spectrometer's "heart," responsible for precisely "splitting" mixed polychromatic light into monochromatic light of different colo...Read more -
Online Raman Spectroscopy Empowers Process Research and Production Control of Hexafluoropropylene Oxide!
Hexafluoropropylene Oxide (HFPO) is a core raw material for the production of high-end fluoropolymers and fluorine-containing fine chemicals, widely used in aerospace, semiconductors, and other high-end fields. The optimization of its production process and the precision...Read more -
Carbon‑Nitrogen Metabolism and Material Balance: The “Mathematical Language” for Fermentation Process Optimization
In our previous article, we discussed the oxygen uptake rate (OUR), carbon dioxide evolution rate (CER), and respiratory quotient (RQ) – the "metabolic stethoscopes" derived from exhaust gas analysis. These tools ...Read more -
Does Light Have a “Fingerprint”? A Beginner’s Guide to Spectroscopy
Have you ever wondered whether light—something we see every day yet can never grasp—might possess a unique "fingerprint," much like each of us? That fingerprint is the spectrum. It is not only proof of light's identity but also the "codebook" that scientists use to explo...Read more
