MULTISAMPLER/wet and MULTISAMPLER/dry
Technical specifications and dimensions.
High sample throughput for laser diffraction sensor HELOS and image analysis sensor QICPIC is mastered with the two fully automated sample handling systems MULTISAMPLER for dry and wet applications. Up to 70 sample vials, each containing up to 39 ml, are fed out of a rack to the sensors. The single samples are identified by laser engraved DataMatrix codes.
MULTISAMPLER is a fully-automated handling-robot working with nearly all kinds of Sympatec‘s disperser. The samples to be measured are delivered on a rack with up to 70 glasses (V-vials) of 39 ml volume each. A unique 2D DataMatrix code offers the identification of each vial. This enables a direct assignment of dispersion and measuring procedures by software, if necassary different for each sample. For the optimum protection of the sample, the V-vials are made of brown borosilicate glass. They are reusable, as the DataMatrix code is laser engraved into a ceramic substrate. The V-vials are sealed by PTFE-silicon septum caps with nearly universal chemical resistance. If 70 samples should not be sufficient, the number can be doubled to 140 by using the Rack-Extension option.
If MULTISAMPLER/wet is used for samples to be measured in wet conditions, a specially designed sampler with a double injection needle is used. This instrument is able to feed particles up to 1 mm in diameter and provides in combination with the specially shaped V-vials an almost complete emptying. So the complete sample is analysed. The septum-caps prohibit a contamination of the environment by the sample or the dispersing media. If appropriate cleaning-cycles are added to the control-program and a switch of the dispersing media is possible offering a flexible adaption to the application.
MULTISAMPLER/dry is best suited for dry samples in combination with dispersers of the RODOS family. In this case a specially designed sampler uses the vacuum generated by RODOS to fluidize and transport the sample. Particle sizes up to 1.5 mm are possible. Again, the special shape of the V-vials in combination with a cyclone-like sampling nozzle enables an almost complete emptying.
Sample transport and sample handling are performed by precise servo drives. As handling times of only some seconds are achieved large numbers of samples can be analysed with nearly no idle-times.
MULTISAMPLER/dry 70 | In this application the MULTISAMPLER is located in front or aside of the HELOS system. The figure shows the sampler moving along the vertical axis into the vial at controlled velocity. The sample is transported through the black hose towards the injector inlet of the dry disperser RODOS/M. A new tray can just hang up on the left hand side with its rail on the rear into the wheels of the drive unit. The sample tray is moved by a friction belt, auto-aligned and processed column by column. The read-out of the 2D DataMatrix code is performed by a camera from underneath the rack. |

MULTISAMPLER/wet 70 | The set-up is similar to the MULTISAMPLER/dry, but now the sampler holds two needles, each connected to a peristaltic pump. Suction and pressure side of the pumps are connected by hoses to the basin of the QUIXEL/L. For this purpose the top glass cover of QUIXEL/L has been replaced to a metal one with two hose-connectors. The needles of the sampler are moving from their protection housing along the vertical axis through the septum into the vial at a controlled velocity profile. The sample is transported by the pumps. As the basin of the QUIXEL/L is used, no extra measures for filling or rinsing are required. |

Sample vials of brown glass are use for dry and wet applications. The sample volume is 39 ml. A sealed cap with septum is provided for wet applications with solvents.

On the bottom every vial is marked with a unique 2D DataMatrix-code for identification of each vial.
Racks with 70 vials are organised in 7 rows times 10 colums.
Rack with up to 70 sample vials
The racks can be extended to 2x 70 vials as an option.
Dry: The vacuum generated by the dry disperser RODOS is used for sample transport.
Wet: Two peristaltic pumps operate simultaneously to fill and empty the vial.
