CT-1Plus compound fertilizer chloride ion analyzer - potentiometric titration method

In the production and quality control of compound fertilizers, chloride ion content is a crucial indicator. Excessive chloride ions can cause serious damage to chlorine free crops such as tobacco, fruit trees, and potatoes, directly affecting crop quality and farmers' income. Therefore, the national mandatory standard clearly stipulates that compound fertilizers with a chloride ion content exceeding 3.0% must be labeled with "chlorine containing" on the packaging. This is not only a regulation, but also a responsibility of enterprises for the safety of agricultural products and their own reputation.

How to quickly and accurately determine the chloride ion content to ensure product compliance and avoid the risk of misuse? The CT-1Plus automatic potentiometric titrator provides you with a standard application solution.

Industry Pain Point: The Difficulty of Precision and Efficiency in Chloride Ion Detection

Traditional chemical analysis methods are cumbersome, time-consuming, and require high technical skills and experience from operators, which can easily introduce human errors. In today's pursuit of efficient production, enterprises urgently need a way to:

Accurate results: The data is reliable and directly serves as a professional basis for product labeling.

Easy to operate: reduces dependence on operators and minimizes human error.

Efficient and fast: Shorten the detection cycle and improve quality control efficiency.

Solution:CT-1Plus compound fertilizer chloride ion analyzer - potentiometric titration method——The combination of precision and efficiency

The CT-1Plus potentiometric titrator is designed specifically for this type of precision analysis. It uses the principle of potentiometric titration to automatically determine the endpoint by monitoring the sudden change in potential during the titration process, avoiding the subjectivity of endpoint determination in traditional methods and ensuring that each detection is accurate and error free.

Why chooseCT-1Plus compound fertilizer chloride ion analyzer - potentiometric titration methodDetermination of chloride ions in compound fertilizers?

1. Excellent precision

Equipped with a highly sensitive Ag-101C composite electrode, it has excellent response characteristics to chloride ions. Combined with high-precision measuring tubes, the titration volume is accurate to the microliter level. As shown in the test data above, the RSD (relative standard deviation) of the three parallel experiments is extremely low, with an average stable at 2.77%, fully demonstrating the excellent repeatability and accuracy of this method.

2. Amazing efficiency

The entire measurement process, from sample dissolution to obtaining results, only takes about 2 minutes. Automated operation of instruments frees up the hands of operators and enables quality control testing to keep up with the fast-paced production line.

3. Minimalist operation process

Weigh and dissolve.

Place the titration cup on the instrument.

Select the preset method and start with one click.

With just three steps, the instrument can automatically complete the entire titration process and directly display and record the percentage of chloride ion content, without the need for complex calculations.

4. Intelligent endpoint judgment

Adopting a differential threshold endpoint mode, the instrument intelligently determines the titration endpoint, avoiding human visual errors. Even for samples with darker colors or turbidity, accurate results can be obtained.

Empirical evidence: Data speaks louder than words

We conducted measurements on a compound fertilizer sample under strict testing conditions (23 ° C, 50% humidity):

Instrument configuration: CT-1Plus potentiometric titrator, Ag-101C electrode, 0.1mol/L standard solution of nitric acid and silver.

Test data:

Sample 1 (0.3948g): Chloride ion content 2.75%

Sample 2 (0.3960g): Chloride ion content 2.77%

Sample 3 (0.3775g): Chloride ion content 2.78%

Final result: The chloride ion content of this batch of compound fertilizer is 2.77%.

Clear conclusion: According to the national standard, the chloride ion content of this product does not exceed 3.0%, and there is no need to label it as "chlorine containing". Production enterprises can use this to package their products and effectively avoid market risks.

Application value: Beyond detection, empowering production

For production enterprises: it is the "gatekeeper" for achieving compliant production and strict quality control, providing iron proof for product labeling and protecting brand reputation.

For quality inspection agencies: It is a reliable tool for issuing fair testing reports and enhancing the credibility of the organization.

For agricultural safety: Avoiding the potential threat of excessive chloride ion fertilizers to chlorine sensitive crops from the source, and safeguarding agricultural production safety.

The CT-1Plus potentiometric titrator is not just an instrument, but also a guardian of your compliance with production and quality commitments.
