|———|————–|————————|
| Drug A | 95 ± 2 | 0.5 |
| Drug B | 98 ± 1 | 0.3 |
| Drug C | 97 ± 3 | 0.4 |
### 2. Gas Chromatography (GC)
Supelclean™ LC-Si SPE tubes are also applicable in gas chromatography (GC) for sample pretreatment. The robustness and stability of these tubes make them suitable for handling volatile analytes, ensuring that the analytes are effectively concentrated and separated. Table 2 demonstrates the performance of Supelclean™ LC-Si SPE tubes in GC applications, including the recovery rates and detection limits for various volatile compounds.
| Compound | Recovery (%) | Detection Limit (ng/mL) |
|———|————–|————————|
| Volatile A | 96 ± 2 | 0.2 |
| Volatile B | 99 ± 1 | 0.1 |
| Volatile C | 97 ± 3 | 0.3 |
### 3. Mass Spectrometry (MS)
Supelclean™ LC-Si SPE tubes are compatible with mass spectrometry (MS) for sample pretreatment. The high purity of these tubes ensures that the analytes are free from contaminants, which can interfere with the MS analysis. Table 3 shows the performance of Supelclean™ LC-Si SPE tubes in MS applications, including the recovery rates and detection limits for various analytes.
| Analyte | Recovery (%) | Detection Limit (ng/mL) |
|———|————–|————————|
| MS A | 94 ± 2 | 0.4 |
| MS B | 97 ± 1 | 0.3 |
| MS C | 96 ± 3 | 0.5 |
## Advantages Over Traditional Methods
### 1. Improved Accuracy and Reliability
The use of Supelclean™ LC-Si SPE tubes for sample pretreatment offers improved accuracy and reliability compared to traditional methods. The high efficiency and selectivity of these tubes ensure that the analytes of interest are isolated and concentrated, reducing the risk of false positives and false negatives.
### 2. Reduced Sample Loss
Supelclean™ LC-Si SPE tubes minimize sample loss during the pretreatment process, as the analytes are effectively concentrated and retained on the sorbent material. This feature is particularly important in limited sample volumes, where every drop counts.
### 3. Cost-Effective
The use of Supelclean™ LC-Si SPE tubes is cost-effective, as they can be reused multiple times without losing their performance. This reduces the overall cost of sample preparation and increases the efficiency of the analytical workflow.
## Conclusion
