High Accuracy SeparationHeart-Cut System
The heart-cut system, a type of Advanced Flow Technology, is a column switching technology for separating out specific components. After separation by the first column, only the components requiring more accurate analysis are loaded into a second column with different properties, and a detector, for further separation and detection.
The secret is accurate pressure control by the switching element which uses a multi-Deans switching system and is connected to the outlet to the first column.
Accurate pressure control by the switching element which uses a multi-Deans switching system
Special software capable of performing pressure control easily
- Patent No.JP5023984:
- This technology automatically calculates switching recovery ratios from the various parameters entered by the user. recovery ratio is a ratio of target components passed through the first column that then flow to the detector or second column.
- Patent No.JP4872901:
- Interlinked operation of two GC units
The various parameter settings can be configured while checking the switching
Information related to the second cycle of analytical conditions configured by he user is displayed on the chromatogram. - Patent No.JP4655661:
- Switching range can be configured by double-click on the chromatogram
- Analysis Example:
- Analysis of Bioethanol Using Heart-Cut System
Improving Analytical ProductivityDetector Switching System
The type of detector that should be used differs depending on the analysis objective and target. The detector switching system, a type of Advanced Flow Technology, is a way of detecting the components eluted from a column by delivering them to multiple detectors with different characteristics.
The secret is accurate pressure control by the switching element which uses a multi-Deans switching system and is connected to the outlet to the first column.

- Analysis Example:
- Analysis of Pesticides Using the Detector Switching System
For Higher Analytical Productivity and More Accurate IdentificationDetector Splitting System
The type of detector that should be used differs depending on the analysis objective and target. The Detector Splitting System, a type of Advanced Flow Technology, is a way of delivering separated components simultaneously to multiple detectors.
The secret is pressure control by a splitting element connected downstream to the columns.
- 1 Splitting Element :
- The form of Sample transmission adopted reduces the impact of dead volume.
The inner surface is inactivated. (Patent No.JP5521293) - 2 Resistance tube :
- Three inner diameters are available.
The splitting ratio is adjusted by the combination of the length and inner diameter of the resistance tube used. - 3 Resistance tube and column connector
- 4 APC:
- controlling the gas pressure in the detector splitting unit
Special software enables easy settings configuration
The splitting ratio can be checked and the conditions investigated while changing the settings for the resistance tube’s inner diameter and length.
- Analysis Example:
- → Analysis of Fragrances by Multiple Detectors—FID and MS-TIC
- → Analysis of Grape Fruit Oil by Multiple Detectors—FID, FTD, and FPD
Reducing Analysis TimesBackflush
Backflush, a type of Advanced Flow Technology, is a way of flushing unnecessary components out of the column and injection port by reversing the flow of the carrier gas after the target compounds have been detected. This reduces the analysis time, enabling the next analysis to start immediately.
Pressure control of the injection port and the backflush element
Special software capable of performing pressure control easily
- Patent No.JP5521293:
- This technology automatically creates a pressure control program from the backflush time configured by the user.
- Analysis Example:
- →Example in Which the Analysis Time is Reduced by Half Due to the Backflush System
