Raman Rxn2 Operating Instructions
Endress+Hauser 7
2 Basic safety instructions
Read this section carefully to avoid danger to individuals or the facility. Additional laser safety information and
hazardous area certification and safety instructions are contained in the Raman Rxn2 Safety Instructions
(XA02700C). See Supplementary documentation → .
2.1 Requirements for the personnel
• Installation, commissioning, operation, and maintenance of the measuring system may be carried out only by
specially trained technical personnel.
• Technical personnel must be authorized by the plant operator to carry out the specified activities.
• Electrical connections may be performed only by an electrical technician.
• Technical personnel must have read and understood these Operating Instructions and must follow the
instructions contained herein.
• Faults at the measuring point may only be rectified by authorized trained personnel. Repairs not described in
this document must be carried out only directly at the manufacturer's site or by the service organization.
2.2 Intended use
The Raman Rxn2 analyzer is designed for use in chemical composition measurements of solids, liquids, or turbid
media in a laboratory or process development environment.
The Raman Rxn2 is particularly suited for use in the following applications:
• Endpoint monitoring of chemical reactions
• Crystallinity monitoring of solid materials
• Critical process parameter monitoring and control in upstream cell culture or fermentation bioprocesses
• Molecular structure and composition of plant-based proteins, dairy solids, and cell-based foods
• Small molecule pharmaceutical polymorph identification and monitoring
Use of the device for any purpose other than that described poses a threat to the safety of people and of the entire
measuring system and is not permitted.
2.3 Workplace safety
• Do not use the Raman Rxn2 for anything other than its intended use.
• Do not drape the power cord over counters or on hot surfaces, or in areas where damage to the integrity of the
power cord may occur.
• Do not open the enclosure of the Raman Rxn2.
• Do not look directly into the laser beam.
• Do not allow emitted laser light to reflect off mirrored or shiny surfaces in an uncontrolled way.
• Minimize the presence of shiny surfaces in the working area and always use a laser beam block to prevent
uncontrolled transmission of the laser light.
• Do not leave unused probes uncapped or unblocked while they are still attached to the analyzer.
2.4 Operational safety
Before commissioning the entire measuring point:
1. Verify that all connections are correct.
2. Ensure that electrical cables and optical fiber connections are not damaged.
3. Do not operate damaged products. Protect them against unintentional operation.
4. Label damaged products as defective.
