Calibrate the pH probe and Measure CRMs (CO2 Reference Materials) Calibrate the pH Meter Rinse the acid cup with DI water and leave inverted on drying rack above sink when finished.Ģ.
Rotate the carousel and empty the HCL cup by removing the HCL amber bottle stopper and carefully pouring the HCL back into the bottle. After three purge cycles, the 100 mL sample cup must be emptied as described in step 5 before continuing to purge the lines. Repeat steps 1-3 until all bubbles are purged. On the titrator touchscreen, select PURGE 3x from the home screen, accept the defaults and push START.Īgitate the tubing by flicking or lightly tapping areas with bubbles to aid their expulsion. Any bubbles must be removed to ensure accurate volume measurements during titrations. Prepare the TitratorĮxamine all red tubing for bubbles. Tip: if no rotation occurs, check the wireĬonnections at the back of the Rondolino. If a sample cup is not already present, press the left blue button on top of the Rondolino (rotates carousel 180˚) and place an empty cup for HCL at position 0. It will perform a brief system check, where the probes will raise, and the carousel will rotate, before returning the probes and carousel to their original positions. Turn the Rondolino on (switch on rear, lower right). Turn the titrator on (button on front of cube). In Github Desktop, select fetch origin in the top right in case any changes were made to the repo previously. Turn on the verizon smarthub for internet access. Login in to the srlab account on the computer next to the titrator. Start LabX Software, Titrator, and Rondolino Lead time for receiving new orders of HCl. Mark, please submit a purchase request for more acid, as there is significant
IMPORTANT: If the volume of HCl is below the halfway Swirl the HCL amber bottle to mix the acid with any droplets that may have condensed onto theĬheck the hose in the HCL amber bottle to ensure it reaches the bottom of the bottle. You will need at least 50mL to process a single sample (30mL for initial purging procedure and ~5mL for each subsequent sample).
DAILY STARTUP PROCEDURES Check ReagentsĬheck the volume of HCl in the amber bottle.
