Copper plating bath liquid chloride ion analyzer CT-1Plus potentiometric titrator

In the complex chemical system of copper electroplating, chloride ions (Cl ⁻) play a crucial "dual role". As an important auxiliary gloss agent, trace amounts of chloride ions can work synergistically with copper gloss agents to produce high-quality coatings with mirror like brightness and smoothness.

Faced with this demand for precise analysis, traditional chemical titration methods are limited by subjective errors in human judgment of endpoints, making it difficult to meet the requirements of modern precision production. The CT-1Plus automatic potentiometric titrator has become a solution for determining chloride ion content in the electroplating industry due to its excellent performance.

Why chooseCopper plating bath liquid chloride ion analyzer CT-1Plus potentiometric titratorDetermination of chloride ions in copper plating solution?

The design concept of CT-1Plus stems from a profound understanding of industrial precision analysis. It is not a simple liquid handling device, but a tireless' analytical expert '.

1. Accuracy and repeatability

The instrument adopts a high-precision measuring tube (optional 20mL), and the minimum titration volume can be accurate to 10 μ L, ensuring the fine operation of titration. As shown in the test data above, three parallel measurements were conducted on the same sample, and the results were highly consistent (61.33, 61.05, 61.53 ppm), with an average of 61.30 ppm and extremely small range. This excellent repeatability (RSD<0.5%) provides a solid and reliable data foundation for process adjustments.

2. Intelligent endpoint determination, bidding farewell to human error

CT-1Plus adopts a differential endpoint determination mode, which intelligently determines the endpoint by monitoring the mutation rate (differential value) of the potential during the titration process in real time, avoiding subjective errors and uncertainties in observing color changes with the naked eye. Users only need to set the parameters (such as a differential value of 200), and the instrument can automatically and accurately find the endpoint, with objective and fair results.

3. Efficient and fast, improving quality inspection efficiency

The entire testing process, from sample preparation to result output, only takes about 3 minutes. For electroplating workshops that require frequent monitoring of the composition of the plating solution, this greatly improves quality inspection efficiency, allowing technicians to make immediate responses to the condition of the plating solution and preventing batch quality problems from occurring.

4. Easy to operate and user-friendly design

The concise software interface allows users to easily edit injection sequences and set titration parameters (such as stirring speed of 200 and droplet interval of 1200ms). Analysts can get started with the operation after a brief training, reducing the threshold for personnel and labor costs in the laboratory.

Instrument configuration specially designed for electroplating analysis

CT-1Plus provides you with a complete analysis system:

Host: CT-1Plus automatic potentiometric titrator - the brain of the control system, accurately controls the titration process and processes data.

The testing process is clear at a glance

The process of using CT-1Plus for measurement is very simple:

1. Sampling: Accurately weigh an appropriate amount of copper plating solution sample (such as 10g).

2. Dilution: Transfer to a titration cup and dilute with 50mL of deionized water.

3. Titration: Place the titration cup on the instrument platform and start the sequence. The instrument automatically performs titration.

4. Result: The software automatically calculates and displays the chloride ion content (ppm), and can print or export detailed reports.
