HBr is unavailable because the toxic gas sensor in the HBR cabinet in the gas vault is faulty. (For safety reasons, we cannot run without a functioning gas sensor.) The gas detector is being replaced, which is planned for Monday, 5/11. If the sensor head also arrives on Monday, as we hope, testing of the system is planned for Tuesday and Wednesday. If all goes as well as planned, then we should have HBr back on Wednesday. We apologize for the inconvenience, but please continue to bear with us as we work on these safety concerns.
