Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Kjeltec™ 8100/8200 Distillation Unit is an advanced laboratory instrument designed for efficient and precise distillation, primarily used in Kjeldahl analysis for nitrogen and protein determination. This Quick Guide, version 6006 3343 / Rev. 3, provides essential information for its operation and maintenance.

Function Description

The Kjeltec™ 8100/8200 unit automates the distillation step in the Kjeldahl method, which involves separating ammonia from a digested sample. The instrument ensures accurate and reproducible results by controlling key parameters such as steam generation, alkali addition, and receiver solution dispensing. It is designed to handle various sample types and volumes, making it a versatile tool for analytical laboratories in food, feed, agriculture, and environmental sectors. The unit's core function is to distill the ammonia from the digested sample into a receiver flask containing an acid solution, preparing it for subsequent titration.

Usage Features

The Kjeltec™ 8100/8200 features a user-friendly interface with a menu-driven system and display icons for intuitive operation. The main menu labels include "Analyse," "History," "Settings," and "Manual," each providing access to specific functions.

• Analyse: This section allows users to select and view programs, start an analysis, and stop an ongoing process.
• History: Users can view a history of past analyses, which is useful for tracking results and troubleshooting.
• Settings: This comprehensive menu enables configuration of various instrument parameters. It includes a program editor for customizing analysis methods, date/time settings, contrast adjustment for the display, language selection, and calibration of the dilution pump. Additionally, users can set up level warnings for reagents and configure steam standby options to optimize energy consumption.
• Manual: This section provides access to manual control functions for specific components, such as the door, dilution system, alkali pump, receiver, tube drain, and steam generator.

Navigation and analysis keys include "Up," "Down," "Start," and "Stop," facilitating easy interaction with the instrument. The display also features status and event icons, including "Notice," "Warning," "Canceled," and "Error," to keep the user informed about the instrument's operational status and any potential issues.

The workflow for an analysis is straightforward:

1. Preparation: Users must first check and prepare samples in the rack(s). This includes verifying the cooling water supply, checking the alkali and water tanks (for Kjeltec™ 8100) or alkali, receiver, and water tanks (for Kjeltec™ 8200), and ensuring the waste tank (if used) is ready. Priming of pumps is also a crucial step before the first analysis.
2. Program Selection: A specific program tailored to the sample type and analysis requirements is selected.
3. Sample Loading: A test tube containing the digested sample is loaded into the instrument, and the receiver flask is placed in position.
4. Program Customization (Optional): Users have the option to edit the selected program to fine-tune parameters.
5. Initiating Analysis: The analysis is started by pressing the "Start" key.
6. Monitoring Progress: During analysis, users can view the progress on the display.
7. Post-Analysis: After all samples are analyzed, routine maintenance is performed.

Maintenance Features

Regular maintenance is crucial for ensuring the longevity and optimal performance of the Kjeltec™ 8100/8200 Distillation Unit. The manual outlines a comprehensive maintenance schedule with daily, weekly, monthly, and yearly tasks, as well as additional maintenance as needed. FOSS offers FossCare support plans, which include regular preventive maintenance by certified engineers, providing a convenient way to ensure the instrument remains in top condition.

  • Cleaning of Tube Adapter: Maintains efficient sample transfer.
  • Cleaning from Spillage: Addresses any accidental spills to prevent corrosion and maintain cleanliness.
  • Check of Sample Racks: Ensures racks are clean and in good condition for proper sample placement.

• Weekly (W):

  • Check of Safety Functions: Verifies that all safety mechanisms are operational.
  • Check of Reagent Tanks: Monitors reagent levels and ensures tanks are clean.
  • Check of Digestion Tubes: Inspects tubes for damage or residue.

• Every 1-3 Months (1-3 M):

  • Cleaning of Alkali Pump: Prevents blockages and ensures accurate alkali dispensing.
  • Cleaning of Splash Head: Maintains efficient condensation and prevents carry-over.
  • Cleaning of Receiver Solution Dispensing System: Ensures precise delivery of the receiver solution.
  • Check of Tube Adapter: A more thorough check than the daily routine.

• Additional Maintenance (Add.): These tasks are performed as needed, often in response to specific issues or after a certain number of analyses.

• Yearly (Y):

  • Cleaning of Steam Generator: A critical annual task to maintain efficient steam production and prevent scale buildup.
