Lithium Hexafluorophosphate Synthesis: The Five Major Pain Points of PF₅ Monitoring
Phosphorus pentafluoride (PF₅) is the core raw material for the synthesis of lithium hexafluorophosphate (LiPF₆). Its concentration, purity, and stability of feed rate directly determine the product yield, purity, and free acid control level. In mainstream process...Read more -
Cells Are “Breathing”: An In-Depth Interpretation of the Physiological Codes of Oxygen Uptake Rate (OUR) and Carbon Dioxide Evolution Rate (CER)
In the sophisticated world of fermentation engineering, we often say that "cells are living factories." The "breathing" of these factories—namely, the energy metabolic activities of cells—serves as the cornerstone for all life activities and product synthesis. Oxygen Upt...Read more -
The “Optical CT” That Penetrates the Microscopic World – SD-OCT at Different Wavelengths: Why Does Each Have Its Strengths?
If medical imaging can be compared to the "eyes" that observe the human body, then X-rays and CT scans reveal bones and internal organs, while ultrasound visualizes soft tissues. SD-OCT (Spectral-Domain Optical Coherence Tomography) , however, is like a "micron-scale opt...Read more -
How Two Mainstream Processes Synthesize Carbonyl Fluoride — A Key Fluorinated Intermediate
Carbonyl fluoride (COF₂), also known as fluorine phosgene, is a colorless, highly toxic gas at room temperature. It hydrolyzes rapidly in water to produce hydrogen fluoride (HF). As an indispensable fluorinated intermediate in the electronics, fluorochemical, and semicon...Read more -
A Checklist for Monitoring the “Vital Signs” of Fermenters: Comprehensive Analysis of Physical, Chemical, and Biological Parameters
If we compare a fermenter to a living organism, then the microbial cells inside it are the "heart" and "brain" of that organism. The fermentation process, in turn, is a precise and dynamic biochemical symphony orc...Read more -
Choosing the Right Optical Fiber for a Spectrometer: A Practical Guide
Selecting an appropriate optical fiber for a spectrometer system is essential for ensuring signal transmission efficiency and measurement accuracy. An improper choice may lead to signal loss or wasted resources. Based on the characteristics of JINSP spectrometers,...Read more -
From Fluorite to Chips: The Fantastic Voyage of a Bottle of Hydrofluoric Acid
The fluorine chemical industry is hailed as the "golden industry." Its industrial chain starts from fluorite mines deep in the earth's crust, journeys through a bottle of hydrofluoric acid in a "fantastic voyage," and finally reaches high-end fields such as chip manufact...Read more -
Bidding Farewell to the “Black Box” Era: Why Do Bioprocesses Need a Pair of “Electronic Eyes”?
In bioprocess fermentation workshops, engineers frequently face a common dilemma: the fermenter before them resembles a vast "black box." We know what goes in and what ultimately comes out, but regarding the complex life activities occurring within the vessel—when microo...Read more -
From M-Type to Crossed Type: The Dual-Track Evolution of Czerny-Turner Spectrometer Configurations
01 Origins: The Classic Design from the University of Berlin (1930) In 1930, Professor Marianus Czerny of the Physical Institute at the University of Berlin, together with his doctoral student Arthur Francis Turner, published a landmark paper that first proposed t...Read more -
Detection of Crude Protein Content in Animal Feed Using Near-Infrared Spectroscopy
On May 1, 2024, the NY/T 4427-2023 "Application Guidelines for Near-Infrared Spectroscopy Determination of Feed" officially came into effect. This standard provides application guidelines for the determination of technical parameters of feed components such as moisture, ...Read more -
Application of Fiber Optic Spectrometer in Food Additive Detection
In modern food industries, food additives are vital tools for enhancing food quality and extending shelf life. There are various types of additives, each with different functions. While they improve the appearance, taste, and nutritional value of food, they also raise concerns about food safety. ...Read more -
Application of Fiber Optic Spectrometers in Sunscreen Clothing Testing
As awareness of health and sun protection increases, sunscreen clothing has become an important product, and its effectiveness is drawing more attention. The effectiveness of sunscreen clothing directly relates to the level of protection it offers consumers against harmf...Read more
