Dotato dell’esclusiva capacità di ionizzazione Tandem®.
Ideale i laboratori che affrontano analisi complesse che necessitano della maggiore sicurezza di identificazione derivante dalla ionizzazione soft e non possono permettersi di scendere a compromessi sulla sensibilità.
L’ulteriore confidenza fornita dalla soft EI si è rivelata fondamentale per l’identificazione di isomeri che sono indistinguibili a 70 eV.

Descrizione

Le prestazioni del sistema BenchTOF-HD abbinate alla rivoluzionaria tecnologia di Ionizzazione a Energia Variabile Select-eV™ Sorgente a energia di ionizzazione variabile

L’innovativa tecnologia della sorgente Select-eV consente di passare dalla convenzionale energia di ionizzazione di 70 eV a energie di ionizzazione inferiori, senza perdita di sensibilità, senza introdurre gas reagenti e senza variazioni hardware.

La sorgente Select-eV è integrata di serie sul modello BenchTOF-Select

I valori dell’energia di ionizzazione possono essere variati dai convenzionali 70 eV fino a 10 eV e salvati come parte integrante del metodo GC/MS.

All’interno di una sequenza di analisi possono essere inseriti metodi con valori di EI differenti senza necessità di alcun fermo o intervento manuale da parte dell’operatore.

Vantaggi:

Acquisire simultaneamente dati di ionizzazione hard e soft usando la tecnologia Tandem Ionisation® – per una produttività senza pari.
Identificare con certezza composti incogniti, e distinguere in routine tra composti strutturalmente simili.
Fornire maggiore confidenza nell’identificazione, grazie agli spettri acquisiti a 70 eV con qualità di riferimento e agli spettri EI complementari acquisiti a più bassa energia di ionizzazione.
Espandere le capacità del laboratorio migliorando la rilevazione di composti a livello di traccia in matrici complesse.
Accelerare l’analisi di campioni complessi con GC e GC × GC veloci.
Ottimizzare il controllo dello strumento, lo sviluppo del metodo e l’analisi dei dati con le piattaforme software TOF-DS ™ o ChromSpace®

Flowmodulated GC×GC with parallel detection by both TOF MS and SCD, for comprehensive screening and highly-specific detection of sulfur species, all in a single run

3 MB

The GCxGC TOF analysis showed a very high sensitivity, but for some compounds the mass spectrum is not specific enough to assure a correct identification. The Retention Index reference is useful to predict the elution order, but the possibility to use a different detector can give better results. VUV detector give additional information to identify, in presence of a large number of isomer, the correct peak.
