Why are Mixing T-Pieces Important in ICP?
The Internal Standard Addition
- Mixing T-pieces are for adding internal standards (ISTDs) to samples. In addition, they are for calibrating solutions online.
- ISTDs are elements or isotopes that are not naturally present, or are at very low levels, in the samples being analyzed.
- They are added at a known, fixed concentration to all blanks, standards, and samples.
- The ISTD signal helps to correct for various factors that can affect the accuracy and precision of the analysis, including:
- Matrix effects: The presence of high concentrations of other elements in the sample can suppress the signals of the analytes of interest.
- Instrument drift: Changes in instrument performance over time can lead to variations in signal intensity.
- Sample transport variations: Inconsistent sample delivery rates can cause fluctuations in the signal.
Compensate for these effects by monitoring the ISTD signal. This leads to more accurate and reliable results.
What are the Advantages of Online Addition?
- Improved precision: Inconsistencies are minimized by mixing the ISTD and sample in line. This is more efficient than associating them with manual addition or separate delivery systems. Plus, it leads to more reproducible results.
- Reduced potential for errors and contamination: Online addition eliminates the need for manual handling and pipetting, thereby reducing the chances of human error and sample contamination.
- Faster analysis: Eliminating manual ISTD addition streamlines the workflow, allowing for faster sample throughput.
Mixing T-pieces for online dilution of samples are particularly useful for samples with high concentrations of dissolved solids that may overload the nebulizer and plasma. Plus, they are also helpful for mixing two reagents for other purposes, like introducing chemical additives or modifying the sample matrix before nebulization.
The Importance of the Mixing T-Piece in ICP
- The proper and consistent addition of internal standards via mixing T-pieces is crucial for obtaining accurate and reliable results in ICP analysis, particularly when dealing with complex matrices or when aiming for high precision and detection limits.
- It improves the overall stability of the measurement, reduces drift, and extends the period between recalibrations.
- Minimizing the effects of matrix interferences and instrument variations is optimal. In addition, mixing T-pieces enhances the robustness and accuracy of ICP measurements.
Mixing T-pieces are an indispensable tool in ICP analysis, facilitating the online addition of internal standards, simplifying sample preparation, improving analytical performance, and ensuring the quality and reliability of the analytical data.
