Intelligent – "The MCP polarimeters use intelligent sample cells and quartz plates," explains Dr. Bertram. "The wireless ToolmasterTM technology automatically transfers the sample cell ID and all parameters to the MCP polarimeter. This saves a lot of time, eliminates user errors and makes every change to the instrument 100 % traceable in the Audit trail, as specified by 21 CFR Part 11." When changing the cell, checking or adjusting the polarimeter, no data needs to be entered manually. The MCP polarimeter also gives a warning if an operator accidently tries to use an incorrect cell for the set method, a feature that is particularly useful for critical measurements.

Insight – To ensure the highest possible traceability of the results and easy instrument handling, MCP polarimeters have the FillingCheck^TM feature. Dr. Bertram explains: "Now there is no need to peer into the sample cell to check for bubbles. A camera inside shows a live image of the sample filling on the touchscreen. The operator sees whether there are any filling errors like air bubbles or particles in the sample and the image can also be stored together with the measured result."

Rock solid – MCP’s high-quality optical components and electronics provide a resolution of up to 0.0001° OR. To achieve the highest accuracy over the entire measuring range the electronic components are mounted onto a rock-solid aluminum bench. As Nils Bertram explains, "The greatest electronics in the world cannot replace proper mechanical design. With MCP, you can rely on the results, even if the instrument has been moved in the lab or sits on an uneven surface. Plastic is not used for any of the sensitive parts in the inside."

Stable temperatures – Powerful temperature control using Peltier elements is now standard with all MCP polarimeters. "As temperature is the largest external influencing factor on optical rotation," reports Nils Bertram, "you cannot specify a high accuracy in optical rotation without having the corresponding temperature accuracy. You want to reach the chosen temperature quickly, keep it absolutely stable and avoid any gradients in the sample cell? This is done by Anton Paar’s unique Peltier jacket enclosing the sample cell for optimal heat transfer." Using a polarimeter with this technology also makes thermostatic water baths obsolete.

Flexible -The MCP polarimeters are modular and therefore extremely flexible. From routine determination of Optical Rotation and Specific Rotation to concentration measurement, MCP provides the right combination of sample cell and wavelength. "Whatever you want, MCP delivers. Up to 6 additional wavelengths can be ordered together with the instrument or installed at a later stage, allowing each MCP polarimeter to be customized to suit any application," says Dr. Bertram.

Qualification and validation – The MCP polarimeters fully support the fulfillment of requirements according to 21 CFR part 11. For customers in the pharmaceutical industry Anton Paar provides a complete qualification and validation documentation package for the MCP polarimeters. As Dr. Bertram explains: "Time is money. With this documentation and a qualification expert from Anton Paar, the polarimeter can be up and running in 1 to 2 days."
