Hard ester acrylic ester moisture analyzer AKF-CH6 Karl Fischer

In the field of fine chemicals and polymer materials, hard ester based acrylic ester is an important monomer, and its purity and moisture content directly determine the performance and quality of the final products (such as adhesives, special resins, plastics). However, due to its physical properties, direct injection analysis is prone to flocculation, which becomes an insurmountable obstacle for traditional moisture determination methods. Launched by Hegong InstrumentHard ester acrylic ester moisture analyzer AKF-CH6 Karl FischerIt is a professional application solution designed to address pain points in such industries.

1、 Why is the determination of moisture in hard ester acrylic esters so difficult?

Hard ester based acrylic esters are usually solid or semi-solid at room temperature and have poor solubility in certain solvents. If direct injection method is used:

Uneven sample: prone to flocculation or precipitation, resulting in the inability of the sample to participate uniformly in the reaction.

Polluting instruments: Aggregates may clog pipelines, contaminate titration tanks and electrodes, significantly increasing maintenance costs.

Result distortion: The reaction is not ideal, resulting in significantly lower or less reproducible moisture measurement results.

These pain points have deterred many laboratories from detecting the moisture content of hard ester based acrylic esters, or they can only rely on indirect and inaccurate methods.

2、 AKF-CH6's winning weapon: integrated design and heating injection technology

AKF-CH6 is not an ordinary Karl Fischer moisture analyzer. It integrates a Coulomb method for water measurement, a precise temperature controlled heating furnace, and an intelligent control system.

Core technological advantages:

1. Fully enclosed heating injection system

This is the key to overcoming the flocculation problem. AKF-CH6 is equipped with a dedicated heating furnace and sealed injection bottle. During testing, the sample is placed in an injection bottle and heated in a stable environment up to 140 ℃ (adjustable temperature). The moisture (and some volatile components) in the sample are fully vaporized, and then accurately and uniformly carried into the titration cell by a dry carrier gas (such as nitrogen). This process avoids direct contact between the sample and the reagent, and fundamentally eliminates flocculation contamination.

2. High precision Coulomb method for measuring water

Using the classic Karl Fischer Coulomb method principle, the water entering the titration cell is electrolyzed and quantified. This method has high sensitivity and accuracy for trace amounts of moisture (as low as ppm), making it very suitable for chemicals such as hard ester based acrylic esters that have strict requirements for moisture content.

3. Intelligent operation experience

One click puncture measurement: The operator only needs to weigh, place the sample bottle into the heating tank, click "start" and "puncture", and the instrument will automatically complete all subsequent processes.

Flexible parameter setting: Users can customize key parameters such as heating temperature, carrier gas flow rate, and stirring speed based on sample characteristics to achieve optimal detection results.

Automatic calculation and recording: The instrument automatically deducts blanks, calculates and displays absolute water content and ppm values, and the data can be directly exported, in compliance with GLP regulations.

3、 Excellent performance of AKF-CH6 in the determination of hard ester acrylic esters

According to actual application data, AKF-CH6 has demonstrated its reliability and efficiency:

High precision and repeatability: Three parallel measurements were conducted on the same batch of hard ester based acrylic esters, with results of 494.8ppm, 512.8ppm, 506.5ppm, and an average value of 504.7ppm, indicating repeatabilityJia.

Efficient and fast: The complete testing time for a single sample is only about 7 minutes, far exceeding traditional methods and greatly improving quality inspection efficiency.

Safe and easy to operate: The fully enclosed titration cell system effectively prevents the volatilization of Karl Fischer reagent and the invasion of external moisture, ensuring the safety of operators and the stability of data.

4、 Wide range of applications

The strength of AKF-CH6 lies in its versatility. In addition to hard ester based acrylic esters, it is also suitable for:

Insoluble/insoluble samples: such as polyolefins, nylon, rubber, etc.

Reactive samples: such as isocyanates, anhydrides, etc.

High viscosity samples: such as epoxy resin, grease, coatings, etc.

Solid powders: such as pharmaceutical raw materials, inorganic salts, catalysts, etc.

5. Conclusion

The Hegong AKF-CH6 moisture analyzer solves the problem of moisture determination for difficult to measure samples such as hard ester based acrylic esters through its innovative integrated heating injection design. It not only ensures the accuracy and reliability of data, but also brings an efficient and safe operating experience, making it an ideal choice for quality control in laboratories in chemical, pharmaceutical, materials and other fields.
