UV-1900i Plus has six basic measurement modes, which offer the optimal solution for a variety of measurements. Measures the photometric value at a single wavelength or multiple (up to eight) wavelengths. Measures a sample spectrum using wavelength scanning. Generates a calibration curve from the measurement of standards, and then calculates the concentrations of unknowns. TActivitv Calculation liannel 5.0 s- 40.0 s Time Course Biomethod Measures changes over time in photometric values at a specified wavelength. Quantifies DNA or protein concentrations. Measures absorbance changes as a function...

Various Functions for Comfortable Daily Measurement Assist Function The instrument assists the user to ensure that measurements are performed using the correct procedure.*1 Verifies implementation of correction Confirms conditions of correction Checks whether or not baseline correction, auto zero correction or cell blank correction has been performed and informs the user if it has not been. Informs the user if the last correction performed is not appropriate for the planned measurement. Informs the user if the UV-1900i Plus is not ready to begin measurement and when starting measurements and...

Startup Validation Function Instrument performance checks can be performed automatically when the instrument is turned ON.*2 This enables even more reliable instrument operation. It can also be implemented in combination with the Wakeup function. *2 This function can be enabled/disabled. The performance check items that can be used with this function are as follows: wavelength accuracy (D2), wavelength repeat accuracy (D2), degradation, noise level, baseline flatness, baseline stability (drift), [EP] Control of Wavelength Accuracy (D2), and [USP] Control of Wavelengths (D2). Network Connectivity...

High Performance to Meet Diverse Needs Low Stray Light Calibration Curve 2.00 Instrument with 1.00 % Stray Light UV-1900 series Linearity will be lost in the high absorbance region due to stray light. UV-1900 series is equipped with Low Stray Light Diffraction Gratings, achieve “best-in-class” low stray light. Stray light is at 0.5 % max. (198 nm), making accurate measurements possible at 1 Abs or more, even in the ultraviolet region. In addition, high-concentration samples can be quantified accurately. The figure on the right is a calibration curve for acetic acid, created with absorbance at...

Spectra can be acquired as fast as 29,000 nm/min. Ultra-fast scanning is effective for tracking chemical reactions in a short time. In addition to the absorbance change at specified wavelengths, spectra can be acquired in a short time with the UV-1900i Plus. Therefore, more detailed behavior can be investigated by observing spectra with the UV-1900i Plus. The figures below show the analysis of the particle agglomeration process when salts are added to silver nanoparticles. Measurements of the 300 to 700 nm region were performed in ultra-fast scan mode. In addition to the decrease of absorbance...

From Measurement to Data Output Improved Productivity of Data Analysis Operations Data analysis and data output operations can be performed at the same time as data measurement. Time spent outputting or analyzing data can also be reduced by simultaneously sending data to an Excel® spreadsheet in real time or saving data as text. The software can also automatically perform postprocessing of measured data, such as processing/correcting spectra, and perform pass/fail judgments of measurement results (automatic spectral evaluation). By specifying various evaluation criteria for measurement results,...
