Your analytical instruments are an integral part of your laboratory processes. How can you ensure their availability whenever needed? What measures can you take to prolong their lifespan and maximize your return on investment?
METTLER TOLEDO's preventive maintenance services protect your instruments thanks to our expertise and tailored procedures, including in-depth inspection.
Analytical instruments are complex and sensitive devices that require regular maintenance to ensure they are functioning accurately and reliably. Failure to maintain your equipment can lead to incorrect measurement results, costly repairs, extended downtime, and lost productivity. Proactive maintenance can help to identify and correct potential issues early before they escalate into major problems. This includes the replacement of worn parts and adjustments where applicable. Furthermore, preventive maintenance helps to improve safety by identifying potential hazards and addressing them before they cause accidents or injuries.
Ultimately, preventive maintenance is a cost-effective way to ensure peak operation and maximize the lifespan of your equipment.
Titration Preventive Maintenance
Depending on your application and working environment, your titration system might be exposed to dust, fumes, elevated temperatures, and humidity, as well as corrosive chemicals. In addition, there are many moving parts, like the burette drive, stirrer, pumps, autosampler, etc., that are subject to wear and tear over time. All this can lead to a loss of accuracy and reliability or even a complete breakdown.
Protect your investment with regular preventive maintenance to avoid unexpected downtime and increase your instrument's lifespan.

The measuring cell is the heart of your density meter or refractometer. A correct adjustment is essential for accurate and reliable measurement results. Changing environmental conditions, aging of the measuring cell, or inappropriate handling of the instrument may affect adjustment parameters, resulting in faulty measurement data.
Avoid such failures with regular preventive maintenance and rest assured that your instrument operates within specifications for an extended period.
If applicable, include automation in your preventive maintenance schedule to ensure proper sample handling as part of the measurement cycle.
Temperature adjustment is crucial for correct melting and dropping point measurements. Depending on the measurement mode (thermodynamic or pharmacopeia), different conditions or correction factors are used to measure accurate melting and dropping points of your sample. Adjustments and calibration are performed using certified reference standards.
Dust and fume accumulation, as well as incorrect sample preparation, may impact the measuring compartment (i.e., furnace, camera, and detection components), leading to instrument malfunction or even breakdown.
Ensure equipment performance and proper functioning with regular preventive maintenance performed by our factory-trained technicians following proven, standardized procedures.

The optical performance of a UV/Vis spectrophotometer determines its application capabilities. Typically, pharmacopeias stipulate the strictest requirements in terms of wavelength and photometric accuracy, resolution, and stray light.
Regular inspection and cleaning of the optical components (lenses, mirror) and measurement compartment (cuvette holder/carousel, micro-volume platform) are essential to maintaining optimal operation and peak performance. Applying periodic preventive maintenance and verification ensures adherence to specification and fit-for-purpose condition, prevents downtime, and enhances the longevity of your UV/Vis spectrophotometer.

FAQs
What is the difference between preventive maintenance and calibration of an analytical instrument?
Preventive maintenance service is designed to identify and address any signs of wear and tear or damage to all system components. It includes visual inspections, cleaning, functional testing, and adjustments, if necessary, to ensure the proper functioning of the analytical instrument.
Calibration uses certified tools and reference materials to ensure adherence to technical specifications and measurement performance. A calibration certificate is issued, providing full traceability and enabling regulatory compliance.
Note that it is strongly recommended to schedule a preventive maintenance service prior to calibration.
Why is preventive maintenance for analytical instruments important?
Preventive maintenance is crucial for analytical instruments because it ensures they function properly and provide accurate and reliable results. Analytical Instruments are often expensive and complex, and any malfunction or incorrect reading can result in costly errors, potentially compromising product quality or safety. Preventive maintenance helps to identify potential issues before they become serious problems and can extend the lifespan of the instrument. It also helps to avoid unexpected breakdowns that can cause delays or even shut down laboratory operations.
Last but not least, preventive maintenance is mandated by numerous regulations, guidelines, and applicable quality systems.
What are the typical tasks of preventive maintenance for analytical instruments?
Preventive maintenance starts with a thorough inspection of the equipment to identify any signs of wear and tear, loose screws or cracks, cables and connections, sockets, and housing. This may include the replacement of parts where applicable. Moving parts are cleaned from dirt and debris and lubricated to reduce friction and ensure smooth movement. Furthermore, comprehensive functional and operational tests are performed to ensure proper functioning, and adjustments are made if required to ensure adherence to technical specifications. A detailed preventive maintenance report is issued, providing full traceability and enabling compliance with regulations and quality systems.
How often should preventive maintenance be performed on my analytical instrument?
The frequency of preventive maintenance depends on the type of instrument, its usage, and the operating environment and condition. In addition, process requirements in terms of result accuracy and reliability may impact the maintenance interval. We generally recommend scheduling preventive maintenance at least once a year. For maximum precision, operation in harsh environments, or 24/7 operation, more frequent maintenance of your analytical instrument is advised.
