Gently push the plug into the receptacle until you hear a “click” sound, which suggests the locking finger is now locked into the locking groove located inside the receptacle. 19 Shea Way, Newark, DE 19713, USA • Tel: +1 (302) 368-7824 • Fax: +1 (302) 368-7830 • Web: www.bwtek.com 290020251-C (2018/09/12) Page 8 of 16 Copyright 2018 B&W Tek, LLC Remove interlock. Pull on the outer housing (NOT the cable or back nut), which will cause the locking finger to disengage from the locking groove, and the plug can be removed. When the safety interlock plug is removed from the system, all electrical power to the laser will be turned off. The safety interlock MUST be inserted before the laser can be turned on. Laser emission will stop if the interlock is removed while the laser is on. 19 Shea Way, Newark, DE 19713, USA • Tel: +1 (302) 368-7824 • Fax: +1 (302) 368-7830 • Web: www.bwtek.com 290020251-C (2018/09/12) Page 9 of 16 Copyright 2018 B&W Tek, LLC Software Startup Please follow the user manual to install BWSpec.

Set suitable integration time (generally thousands of milliseconds). Adjust it until the highest peak is around 50000 counts. 2. Take dark scan, and then take additional scan of the sample. Be sure spectrum type is set to “Dark Subtracted” if dark scan is applied. 3. Save data as .txt or .spc (as preferred). Warning:  Be sure to wear laser goggles at all times and avoid looking into laser beam.  Turn off fluorescent lamp or any ambient light which would bring noise signals into spectrum.  Lower the laser power if sample is dark or thermo-unstable such as plastics and explosives. 19 Shea Way, Newark, DE 19713, USA • Tel: +1 (302) 368-7824 • Fax: +1 (302) 368-7830 • Web: www.bwtek.com 290020251-C (2018/09/12) Page 15 of 16 Copyright 2018 B&W Tek, LLC Strong Raman Signal Given: Active Pharmaceutical Ingredients; Alcohols; Antibiotics; Antioxidants; Buffers; Coatings; Dilutants; Emulsifiers; Excipients; Lubricants; Preservatives; Solvents; Vitamins; Monomers and Polymers; Organic Materials; Polyatomic Inorganics (i.e. Calcium Phosphate, Sodium Bicarbonate & Titanium Dioxide) Weak Raman Signal Given: Materials that are Dark in Color; Highly Fluorescing Molecules; Fillers/Binding Agents; Thin Walled Plastics; Water; Glass No Raman Signal Given: Black Materials; Metals; Mono-atomic Ions 19 Shea Way, Newark, DE 19713, USA • Tel: +1 (302) 368-7824 • Fax: +1 (302) 368-7830 • Web: www.bwtek.com 290020251-C (2018/09/12) Page 16 of 16 Copyright 2018 B&W Tek, LLC Document Outline Diagrams of the i-Raman Plus
