The Optic 3 injector is a versatile tool for the Shimadzu GC and GC–MS product range. It features no discrimination and low thermal degradation of the sample.
The Optic 3 injector is a versatile tool for the Shimadzu GC and GC–MS product range. It features no discrimination and low thermal degradation of the sample.
Key features:
Direct heating Ohmically (unique)
Many different liners
Cold injections
Rapid large volume injections (RLVI)
Direct thermal desorption
Automated liner exchange (LINEX)
Direct heating Ohmically with low thermal mass allows:
High temperatures (up to 600 ºC)
Fast ramp rates (up to 30 ºC/s)
Relatively large liner inner diameter (3.4 mm i.d.)
Fast with cooling option LCO2: -50 ºC, LN2: -180 ºC
Fast cooling with external air
The large inner diameter (i.d.) of the liners avoids the problems encountered when using a PTV of small i.d., such as limitations in injection volume, no possibility for solids or inserts and low break-through volumes in thermodesorption. Special liners such as sintered glass liners for pesticide analysis are available. Using the LINEX (Automatic Liner Exchange) with the AOC-5000 autosampler the system can be fully automated.

The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
