Nexera SR is configured with the new SPD-M30A photodiode array detector. The new peak calculation technology, i-PDeA (Patent pending), proposes a new approach for separation of co-eluted peaks and extraction of impurity peaks from main peaks. The superior sensitivity and resolution expand the range of UHPLC analyses.


Intelligence in UHPLC/HPLC Analysis

Complete Separation of Co-eluted Peaks by intelligent Peak Deconvolution Analysis (i-PDeA, Patent pending)

i-PDeA enables the extraction of a single peak from co-eluted peaks by utilizing difference in spectra by a few steps. The new separation method removes discussion of integration methods for co-eluted peaks. The i-PDeA also helps detect impurity peaks in a target peak.



Ultimate Sensitivity


Achieving maximum sensitivity

The SPD-M30A photodiode array detector adopts the high-sensitivity and low-dispersion capillary cell, SR-Cell, which achieves a 0.4×10-5 AU noise level. The SPD-M30A offers ultimate in UHPLC analysis, realizing high-sensitivity and high-resolution.



The excellent sensitivity and wide dynamic detection range enables simultaneous analysis of a main ingredient and impurity of 0.005% content.

Maximized Resolution

Superior spectrum resolution and linearity

The SPD-M30A provides unrivaled spectrum resolution by adopting an optimized optic system. In addition, the new signal treatment technology realizes excellent spectrum linearity across a wide area from low concentration to high concentration. The SPD-M30A supports analyses, such as purity analysis, that require a wide dynamic range.


Unrivalled Stability

Baseline stabilization by temperature-controlled TC-Optics

The SPD-M30A adopts the new temperature-controlled TC-Optics with the SR-Cell that has an optimized heat exchange inlet pipe. These features achieve faster stabilization times low external dispersion for UHPLC analysis. The faster stabilization shortens the “wait time” for analysis, thereby increasing total analytical throughput.


Stable performance against room temperature shift

The SPD-M30A incorporates TC-Optics to achieve a more stable baseline against room temperature shifts.
