Greater Efficiency, Greater Ease of Use
Reliable Data Acquisition Even During High-Temperature Analysis
Using an Automatic Pretreatment Function to Improve Operational Efficiency
All i-Series Plus models now come with an automatic pretreatment function. By simply entering items on a template, the automatic pretreatment function can perform operations such as automatic sample dilution, reagent addition, and sample co-injection with an internal standard substance. Since all pretreatment operations are performed by the system, stable results can even be obtained by users unfamiliar with the process, and samples can be analyzed over the weekend or at night without needing human supervision, which promises to achieve substantial improvements in operational efficiency.
Dilution Function Automates the Process of Calibration Curve Creation to Unknown Sample Quantitation
The dilution function can dilute a sample to a specific dilution ratio. As an example, the dilution function can be used to automatically create a calibration curve by simply placing a standard stock sample solution in the autosampler and specifying the desired dilution ratio. It can also be used to analyze unknown samples consecutively, and output reports containing the quantitation results.
A Co-Injection Function with Various Applications
The co-injection function prevents peak shape degradation by co-injecting the sample and diluted solution together.
As an example, when the sample solvent is a high-concentration organic solvent, the injection volume can affect the sample solvent and lead to a degradation of peak shape. In these situations, co-injecting the sample and diluting solvent together can prevent peak shape degradation. This problem is more pronounced the smaller the internal diameter of piping used in the UHPLC system, but the co-injection function allows analysis to be performed without replacing piping.
Pre-Column Derivertization for Amino Acid Analysis
Using the co-injection function allows a sample to be reacted with reagent within the injection needle. The chromatogram below shows the results of using the co-injection function to perform a pre-labeling reaction with amino acid OPA reagent. The entire aspirated sample is delivered for analysis, reducing the sample and reagent volumes required by analysis to a minimum and also allowing for a highly sensitive analysis.
Excellent Baseline Stability: Dual-Temp Control with TC-Optics and Flow Cells
Assists Analysis over Wide Concentration Range: Linearity and Reproducibility of Injection Volume
The i-Series Plus provides highly precise data in micro volume injections of 1 μL or less. This system allows the direct injection of the concentrated samples without dilution to save the preprocessing operation. In addition, the superior injection volume linearity improves the reliability of data for a wide range of injection volumes.
Ultra-Low Carryover Performance Enables High-Sensitivity Analysis
System-to-System Reproducibility Improves Data Compatibility
In addition to its reproducible performance on a single system, the i-Series Plus's excellent system-to-system reproducibility further improves data reliability. With its unsurpassed performance in areas such as solvent delivery precision, concentration accuracy, and injection volume accuracy, the i-Series Plus is now a new industry standard for global labs.
