There are several types of sampling systems used in catalysis, including:
1. Manual Sampling Systems: These systems require manual intervention to collect samples. While they are simple and inexpensive, they can be labor-intensive and prone to human error.
2. Automated Sampling Systems: These systems automatically collect samples at predetermined intervals, offering higher accuracy and reliability. They are ideal for continuous or long-term processes.
3. In-line Sampling Systems: These systems allow for continuous monitoring of the reaction mixture without interrupting the process. They are highly efficient and provide real-time data but can be expensive to install and maintain.
