Multifunctional Autosampler

The wide range of injection modes offered by the OPTIC-4 multimode inlet makes it possible to accommodate many different forms of samples. So, in addition to split/splitless injections, many others, such as the pyrolysis analysis of solid samples and the thermal desorption analysis of odor components, can be performed.

Simplifying Pretreatment—DMI
(Difficult Matrix Introduction)

With DMI, a microvial containing the sample is inserted in the liner, and the liner is then heated at the injection port before analyzing the sample. Since, by adjusting the temperature of the injection port, non-volatile impurity components are left remaining in the microvial, GC/MS measurements are performed with a minimal amount of pretreatment.

After Trapping/Concentration Using MonoTrap, Thermal Desorption Provides High-Sensitivity Analysis

By using the MonoTrap*3 that has a monolith silica structure and a high trapping efficiency to trap volatile components in the sample, then using the OPTIC-4 for thermal desorption, analyses that are higher in sensitivity compared to the solvent elution method can be performed. Moreover, the high-speed heating function provides for rapid desorption of the trapped components, which results in acquisition of sharper peaks.

The liner placed in the rack, after removing it's caps at the CDC station, is installed in the OPTIC-4 injection port.

Sharper Peaks, Enhanced Separation

Intuitive Operation Using Dedicated Evolution Workstation Software

The dedicated Evolution Workstation software for the OPTIC-4 displays analysis conditions in a time chart for intuitive grasping and modification, so formulation of conditions is easy. Optimization is easy, since methods accommodating various injection modes have been included.

Wide Variety of Injection Modes

Since there are injection modes designed for various forms of samples, many different forms of samples can be analyzed.
