CT-1Plus color titration titrator for measuring high concentration of hydrofluoric acid

High definition camera intelligent color recognition, differential algorithm precise determination of endpoint, one click replacement for high-risk manual operation.

In semiconductor manufacturing, glass etching, and chemical production, hydrofluoric acid is a key process material, and its concentration control directly affects product quality and production safety. However, the high corrosiveness and toxicity of hydrofluoric acid make traditional manual titration operations full of risks: personnel are exposed to hazardous environments, subjective errors exist in visual judgment of endpoints, and the repeatability of high concentration sample determination is poor, which have always been common challenges faced by the industry.

To solve this problem,CT-1Plus color titration titrator for measuring high concentration of hydrofluoric acidAs a result, a high-definition camera color titration module has been specially integrated, achieving automation, high precision, and safety in hydrofluoric acid concentration determination, becoming an ideal solution to replace manual titration.

1、 Why is it necessary to replace manual titration with hydrofluoric acid?

1. High safety risk: Hydrofluoric acid can cause serious burns or even systemic toxicity through skin contact, respiratory inhalation, and even accidents with slight carelessness in manual operation.

2. Difficulty in determining the endpoint: The turning point of the color change stage (colorless → pale pink) of the phenolphthalein indicator is difficult to accurately capture with the naked eye, especially for darker or turbid samples, which can easily lead to over dripping or insufficient titration.

3. Low efficiency and consistency: Manual operation is time-consuming and labor-intensive, and the results are greatly affected by the operator's experience and fatigue, making it difficult to meet the needs of modern laboratories for high-throughput and high repeatability testing.

2、 How does CT-1Plus achieve automation in hydrofluoric acid determination?

The core of the instrument lies in the deep integration of its high-definition camera color recognition system and intelligent differential endpoint determination algorithm.

1. Visual replacement of human eyes:

The high-definition camera captures the subtle color changes of the solution in the titration cup in real time, converts the image information into digital signals, and avoids human visual errors.

2. Algorithms replace the human brain:

The instrument is equipped with intelligent software for real-time analysis of color change rate (Δ E/Δ V), which can automatically determine the endpoint at the inflection point of color change (the point of maximum differential value) without waiting for obvious color changes, resulting in more scientific and accurate results.

3. Automation replaces manual labor:

From precise liquid addition, stirring and mixing to endpoint judgment, data recording and calculation, the entire process can be started with one click and automatically completed. Operators only need to weigh the sample to stay away from hazardous environments, significantly reducing exposure risks.

3、 Instrument features and advantages

-Accurate and reliable: The minimum titration volume is 10 μ L, and the high-precision measuring tube ensures accurate results; The measured data shows that the difference between parallel samples is less than 0.1%, indicating good repeatability.

-Safe and intelligent: unmanned operation throughout the process, preventing personnel from coming into contact with hydrofluoric acid; Intelligent algorithms avoid subjective errors and ensure data reliability.

-Efficient and convenient: A single measurement only takes about 3 minutes, greatly improving detection efficiency; The method can be saved and called with one click, reducing the threshold for operation.

-Wide applicability: Not only suitable for hydrofluoric acid, but also for other strong acids, strong bases, or titration analyses that require color endpoint determination.

4、 Measured data speaks for itself

Measure a batch of hydrofluoric acid samples in a strictly controlled laboratory environment (25.1 ° C, 53.5% RH):

The data proves that CT-1Plus exhibits excellent accuracy and repeatability in measuring high concentrations of hydrofluoric acid.

5、 Application Fields

This instrument and method are an ideal choice for the following fields:

-Semiconductor industry: wafer cleaning, etching solution concentration monitoring and quality inspection.

-Chemical production: concentration determination of fluoride products such as hydrofluoric acid and ammonium hydrogen fluoride.

-Glass processing: Formula control and incoming inspection of hydrofluoric acid solution for etching glass.
