Nexera FV - Features

Everything is automated in dissolution testing systems containing the Nexera FV, from sampling, dilution, and other pretreatments to data acquisition, data analysis, and the creation of reports. As a result, there is less hands-on work for the operator, thereby supporting an increase in processing throughput. Further, there is no manual dispensing of samples, so sampling mistakes are eliminated, enabling safer testing.

Typical System Configuration for Online Dissolution Testing

 

Direct Injection Mode: Exclusively with the Nexera System

This mode directly injects and analyzes the test solution sent from the reaction flask or dissolution tester vessels. It is effective if the analysis of the injected reaction mixture or test solution is completed by the next sampling interval. This analysis mode can be selected because the Nexera FV is compatible with UHPLC analysis.

Fraction Mode: For Confirmation at Short Sampling Intervals

This analysis mode is used for tests in which the sampling interval is short. Thanks to the high-speed operation delivered by the Nexera autosampler, the system is compatible with sampling intervals as short as 5 minutes. Up to 384 samples can be fractionated. This is effective when dilution will be required.

 

Automatic Dilution of High-Concentration Samples

 

High-concentration samples often require dilution. Samples can be diluted online using the fraction analysis mode. High injection accuracy is provided even at trace quantities, enabling reliable automatic dilution. The table to the right shows the dilution accuracy of standard solutions using Nexera FV's automatic dilution method. (Sample: Aqueous caffeine solution)

 

Automatic Addition of Internal Standard Substances

 

Internal standard substances are sometimes added to samples for the purpose of yield calculations. Using the Nexera FV automatic pretreatment function, a set amount of an internal standard substance can be automatically added to and mixed with the injection sample, after which the mixture can be injected onto a column.

One System Plays Two Roles, Significantly Improving the Throughput of the Testing Lab

The Nexera FV is a multipurpose system since not only can it be used online as an LC by connecting it with a reaction vessel and dilution tester, but also as a standalone UHPLC system. This maximizes the equipment operation rate, increasing the utilization of laboratory assets.

 

Long-Lasting Consumables Provide for High Cost-Effectiveness

 

A special septum is used for the flow through vial that receives the dissolution medium. It boasts a better degree of adherence after needle penetration in comparison to a regular septum, and can be used for 200 continuous injections without leaking.* This greatly reduces maintenance, enabling continuous testing.

*The replacement period varies depending on the usage conditions.

LabSolutions FV

Easily Implement Batch Synthesis, Flow Synthesis, Dilution Tests, and Other Online LC Analyses

When monitoring is performed with an online LC, one of the laborious tasks that must be performed is the creation of an analysis schedule corresponding to the sampling conditions. The special LabSolutions FV software provides strong support for a range of time-consuming tasks prior to starting analysis. In a single software window, not only can the user configure the LC analysis conditions, sampling interval, and other necessary information, but the LabSolutions analysis schedule can be created automatically, so online LC analysis can be started just by clicking the Start button. This reduces the time and labor expended prior to starting analysis and, at the same time, reduces the risk of analysis failures due to setting mistakes, thereby contributing to a more efficient workflow and improved data reliability.

• Automatically creates analysis schedules in accordance with the sampling conditions.
• Implements fraction and dilution automatically with the autosampler pretreatment program.
• Sampling can be started by an external signal input or at a specified time.

Heightened Efficiency of the Entire Monitoring Analysis Workflow

Generally, in the later part of an online analysis schedule, the sampling interval becomes larger, and the LC instrument remains idle for longer periods. Using the automatic analysis insertion function provided by LabSolutions FV, when idle periods arise during sampling, LC data analysis of samples that have already been sampled is automatically conducted during the set analysis schedule, heightening the efficiency of the entire online analysis.

 

Online Confirmation of Analytical Results with Trend Plots

Using the multi-data report function, which can create and output reports in a spreadsheet-like format, the results for changes over time to the yield of the principal components of the synthesis, the creation of intermediate products, and the dilution rate in dilution testing can be output automatically.
