PAL DHR Dual Head

PAL DHR Dual Head

Productivity x 2

Time is money. To maximize productivity the PAL DHR performs tasks with two heads in parallel

Brochure

System description

Two heads can move independently.

The heads can execute two independent workflows:
- Headspace with sample preparation, e.g. standard addition or derivatization
- High throughput parallel injections into two GC- or LC-systems

- The software optimizes the timetable to maximize productivity
-Automatic collision control ensures process safety and easy programming
-120 or 160 cm wide working area
-Combinations of RTC/RSI heads
-With an RTC head toolchange expands the options further

PAL RTC/RSI Benefits

Robotic Tool Change for productivity (PAL RTC only)

  • ● Automatic selection of the syringe with optimal accuracy for adding standards or preparing serial dilutions

  • ● On the fly switching between a syringe tool for the addition of an internal standard and the LC-MS Tool for subsequent Analysis

  • ● Possibility to permanently configure several workflows on one system for a walk-up prep station, e.g. Liquid/Liquid Extraction and Solid Phase Extraction (SPE)

  • ● Automated optimization of methods e.g. by selecting the most suitable Solid Phase Micro Extraction (SPME) fiber from an array of 4 different ones

  • ● Derivatization reactions performed without manual intervention for productivity, protection against hazardous chemicals and process safety

  • ● Automation of labor intensive manual workflows like protein digestion

Robotic Tool Change for productivity (PAL RTC only)

Increased Vial Capacity

  • ● 162 x 2mL or 60 x 10mL or 20mL vials/tray holder, other vial types and microtiter plates can be handled
  • ● With temperature controlled stacks a maximum of 9216 samples out of 24 MTP's can be handled
  • ● Cooled Stack with position control

Increased Vial Capacity

Minimized carryover and reproducible injection of minute sample volumes

Minimized carryover and reproducible injection of minute sample volumes
Bottom sensing makes sure that small volumes can be injected out of a few µL of sample (e.g. 3 x 1 µL out of 5 µL).
Minimized carryover and reproducible injection of minute sample volumes
With Constant Force Technology the PAL detects the correct position of the needle in the specially designed needle seal. Potential carryover is avoided.

Process Safety

Position detection means process safety. Missing vials or the correct position of the injector are detected and traced.Position detection means process safety. Missing vials or the correct position of the injector are detected and traced.
 

Position detection for the temperature controlled stack ensures that the drawer is in the correct position (open / closed) and the temperature is monitored.

Process Safety

Discrimination free GC Injection

Ultrafast injections down to 100ms reduce discrimination in GC down to C40/C20 > 0.98.

Efficient Mixing

For the efficient mixing during liquid homogenization and extraction steps
  • Magnetic transport of vials
  • Standard vial sizes: 2mL / 10mL / 20mL
  • One additional slot for custom vials
  • Provides efficient 2-phase mixing
