Oligo HTCS

Introducing the first fully-automated systems for oligonucleotide LC/MS!

The Oligo HTCS family of instruments are the only LC/MS systems designed to automate every aspect of oligonucleotide mass spectral analysis. The HTCS takes care of sample injection, desalting, detection, as well as data processing and reporting. With a sample throughput of up to 3000 samples/24 hrs, no LC/MS system on the planet is as productive as the Oligo HTCS. The HTCS allows you to characterize long (>120mers) or fragile oligos that are not amenable to MALDI-ToF. In fact, the HTCS is the only fully-automated MS system which can effectively QC oligos to be used in longmer DNA microarrays. Just as easily, the HTCS can also perform detailed LC/UV/MS profiling on your high-value oligos to give you full information about impurities, degradants, and failure products. Our ProMass software ties it all together, allowing you to process and communicate your results effortlessly.

Applications include:

  • Oligonucleotide manufacturing quality control
  • Diagnostic oligonucleotides
  • Oligo therapeutics
  • RNA and RNAi

System Highlights

A choice of system configurations is available. Simply choose an appropriate system that is matched to your throughput, applications, and budget requirements.

  • The standard Oligo HTCS Ultimate is truly a unique system for oligonucleotide analysis. The system will analyze 1500 samples/24 hrs in high-throughput mode, but has the flexibility to be automatically switched from high-throughput to detailed LC/MS profiling mode from within a sample list run. The HTCS is also fully upgradeable to our HTCS Twin system when you need more throughput.
  • The Oligo HTCS Twin Ultimate is designed for those who need the highest possible throughput and highest quality in oligonucleotide mass analysis. The Twin system employs a dual-arm autosampler to achieve a throughput of >3000 samples/24 hrs in mass confirmation mode.


Features & Benefits

All of our Oligo HTCS systems offer the following:

  • Analyze oligos from n=1 to n>120 bases in length
  • Analyze oligos that are difficult or impossible to analyze by MALDI-ToF, including long oligos (>50 bases), oligos with labile chemical moieties (e.g., BHQ’s), poly-T’s, hairpin oligos, etc.
  • Perfect for the QC of long oligos to be used in DNA microarrays or other applications
  • Analyzes both DNA and RNA oligos, particularly useful for analysis of siRNA oligos, including duplex oligos containing high salt concentrations
  • Routine mass accuracy of 0.01% (1 Da in 10 kDa) across entire mass range of oligos analyzed
  • Automated analysis includes built-in desalting for each oligo analyzed
  • Analysis throughput 1500 samples/24 hrs (3000 samples/24 hrs with Twin configuration)
  • Less expensive to operate (per sample) than high-throughput chip-based MALDI-ToF systems
  • Detailed profiling mode provides full information about impurities, failure sequences, and degradants
  • ProMass software processes entire sample lists without user intervention. ASAP processing allows automated data processing after each sample is analyzed (i.e., real-time processing)
  • Web-based results summary including color-coded sample browser viewable from any web-browser
  • Excel-based sample list import and results summary
  • XML output aides in capturing results for LIMS or database
