ThenanoElute 2 covers a broad range of applications from single-cell to high-throughput routine proteomics. This next generation system provides you with the highest chromatographic resolution resulting in exceptional peptide identification and quantification.

In combination with the timsTOF HT reliable performance was achieved for all injected quantities (see Figure C). This within a 41 min runtime method for 1600 ng K562 tryptic digest by data dependent acquisition parallel accumulation serial fragmentation PASEF (DDA).

With its unique valve design the nanoElute 2 enables software-controlled flow paths for dynamic inclusion of the trap column and backflushing the sample for sharper peaks. It retains the top desirable functionalities of its predecessor ensuring:

Automatable sample preparation procedures alleviate the need for manual intervention can be configured based on user-defined input settings. The following liquid handling functionalities provide the means to dissolve and mix samples just prior to LC-MS analysis:

The timsTOF SCP in combination with the nanoElute 2 UHPLC system achieves unprecedented sensitivity. About 4000 protein groups and over 22,000 precursors were identified from 1 ng of HeLa using a 80 min runtime method (i.e. gradient length of 66 min) and a data-independent acquisition parallel accumulation serial fragmentation (dia-PASEF).

Use the nanoElute 2 and the timsTOF SCP for end-to-end single cell label-free proteomics workflows. The nanoElute 2 injects directly from the label-free proteoCHIP holder used in the cellenONE cell sorter. In this workflow up to 144 single cells can directly be transferred from the cellenONE to the nanoElute 2 autosampler, after sorting and preparation, without pipetting steps, for ultra-sensitive proteomics analysis using the timsTOF SCP and TIMS-DIA-NN.

Assessment of sample pick-up of 250 pg and 1 ng in 1 μL total volume, and 2 ng in 2 μL total volume of peptides from a HeLa cell lysate digest directly injected from wells of the label-free proteoCHIP showed excellent reproducibility in protein group and peptide identification rates. Injections from the label-free proteoCHIP and from an autosampler vial demonstrated comparable results on protein group and peptide identification rates at different peptide concentrations and volumes.

"The simple-to-use nanoElute 2 LC system coupled to a timsTOF Pro has significantly enhanced our protein IDs in comparison to our other platforms. Coupled to superb Aurora column separation, it looks to be a step change in chromatographically resolving isobaric phosphopeptides, enabling even more unambiguous phosphosite annotations."

"The combination of the nanoElute 2 with a timsTOF SCP enables the reproducible identification of >1300 proteins from only 62.5 pg of HeLa digest, making this an optimal platform for our most challenging proteomics and immunopeptidomics projects."

"The nanoElute 2 autosampler is providing key benefits for our clinical research proteomics pipeline. It enables us to monitor the LC performance and now perfectly supports 96 or 384 well plates coming from our robotic platform. The tryptic peptides are directly dissolved in the plate prior to injection, avoiding manual intervention and thus streamlining our workflows."

Laura is the ideal software package whether the work involves metabolite profiling, quality control, compound purification or any other chromatography task. It offers users the facility to create and edit methods, set up sample runs and view data collection across the network, in real time and without being confined to the bench-top PC.

Laura 6 offers full control of the radiochromatography process in a simple, easy to use format. Using a simple wizard driven process for multiple steps Laura is as intuitive to use for the occasional user, as it is for the researcher that uses Laura every day.

Laura 6 has all the features an experienced chromatographer expects - multiple trace display and data treatment, quench correction, decay correction, manual and automatic peak finding, scintillator pump control, fraction collector control, multiple run overlay.

Laura 6 can be installed and configured to meet the most rigorous regulatory compliance. Featuring configurable audit trail, multi level security, e-signatures and data storage into a secure database environment Laura is the radiochromatographers answer for regulatory compliance.

Laura 6 provides connectivity to the widest range of detectors and chromatography systems. With a wide range of detectors supported including the Beta-RAM for radioactivity detection along with chromatography systems for HPLC, TLC, GC as well as multi channel analysers for nuclide identification Laura is truly the data system for all your chromatography requirements.

Laura is designed to fully support GLP and associated regulatory compliance. This includes support for FDA 21 CFR part 11. Totally configurable to meet all requirements, Laura features audit trail, flexible security settings, multi-level access and e-signatures.

Laura has a fully featured audit trail that can again be configured to suit the requirements of the user site. Response from the user can be a simple as choosing from a pre-defined list of standard audit reasons or require a unique response depending on the situation and site rules.

Laura features multi-level access control and the system can be configured to have as many levels of access as the user site requires. Menu items are then restricted according to the security level of the individual logged in.

Laura can be configured to suit your particular site requirements for security. User names and passwords can be controlled relative to the site requirements as can inactivity time outs and all other functions required for a secure system.

Regulatory compliance is an essential feature of Laura, built to meet GLP/GMP, MHRA and FDA 21 CFR part 212 / 11 requirements. Featuring configurable audit trail, electronic signatures, secure data storage in a database environment and multi-level security Laura Radiopharmacy can be configured to meet regulatory requirements for data integrity.

Laura collects data digitally from the radio detectors and HPLC detectors. Digital data collection provides the most accurate and sensitive data interpretation. Additionally radio data is recorded in value per time point such as cpm, cps, dpm.

Laura allows the user to display and analyse multiple chromatograms in the same view. A useful batch analysis tool allows the researcher to quickly analyse multiple data sets using the same integration method.

Laura features a summary table function which allows researchers to run comparisons across a range of chromatograms. Powerful tools such as pivot tables are available to help the user produce comprehensive summary tables.

Laura software takes a digital signal which gives a discreet value every datapoint eg 1s. This gives far greater accuracy and a more detailed chromatogram than a basic analogue signal can. Also digital data collection into Laura is auto ranging over several decades eliminating range setting errors and lost data.

Yes, Laura offers a true single point of control solution for your radiochromatography workstation. By controlling both detector and separation modules Laura simplifies the procedure because you create one method, one batch get all the data in one result file with all associated meta data.

Integration for Medium to High Throughput HPLC PurificationBy: Rob Darrington, Product Manager, Genevac Ltd., Paul de Fraine, Group Leader, Chem Tech Group Syngenta and Mike Jones, Group Leader, Scynexis Europe Ltd.

In the modern purification laboratory, many thousands of novel drug-like compounds are being purified each week.Preparative high performance liquid chromatography (HPLC) is the method of choice. A major issue within the laboratory is traceability of each compound, tube, and fraction. What are the costs of confusion in the laboratory? Lost sample, lost time, lost money, lost contract, lost job?

Typically, a 5 to 10mg injection of compound will produce anywhere between 2 and 5 fractions, depending upon various factors, including; initial purity of sample, method of triggering fraction collector, pump speed and fraction collection tube volume. This begins to create a sizeable problem. Even in a lower throughput lab, this is clearly a huge increase in number of tubes to track. Downstream of HPLC samples need to be analysed, often a daughter sample is taken for analysis which is another doubling in sample numbers. The problem has become much worse!The remainder of the process is usually simple, drying, redissolving, and combining to obtain one final sample of pure compound, usually in a new tube, vial, or plate well. What are the options for managing traceability? This article looks at some of the options and studies the processes of two leading companies who have developed successful solutions.
