Achieving effective EtO abatement in problem areas like office spaces and laboratories on discrete HVAC circuits, and warehouse areas with freestanding finished goods, has been particularly challenging. This white paper discusses the performance of a new, low-power, photocatalyst-based technology for abating EtO in these settings—Sonata Scientific’s HeliosTM EtO control technology platform—with performance validated using the demonstrated capabilities of Picarro’s EtO Workplace Monitoring System (WMS).

In this white paper, we discuss the rescaling of, and establishment of a traceable calibration for, formaldehyde (H2CO) on Picarro’s G2307 “LBDS” Cavity Ring Down Spectrometers.

This white paper describes destruction efficiency testing run by Carus and Picarro, Inc. on Carus’s CARULITE® 500 catalyst media using Picarro’s Ethylene Oxide (EtO) Cavity Ring-Down Spectrometer (CRDS) technology. Picarro’s technology provides industry-leading sensitive, accurate, and virtually drift free measurements at levels reaching below a part per billion, making it an excellent choice for studies where high levels of destruction efficiency need to be characterized and confirmed.

This paper outlines the regulatory framework behind the upcoming changes in the Commercial Sterilizer NESHAP (40 CFR 63 Subpart O). We will discuss how the US EPA decided on the continuous emissions monitoring requirements – including what those requirements are. Many in the sterilization industry have concerns about how to meet these requirements as previous technologies have struggled to demonstrate the response necessary to demonstrate compliance.

This white paper outlines testing performed using Picarro’s continuous emissions monitoring system (CEMS) on a LESNI EO Catalytic Abatement Plant (CAP). This testing was performed at a medical device manufacturer and sterilizer facility in the United States during an active sterilization process. Ethylene oxide (EtO, EO) concentrations were measured in real time upstream of the Catalytic Oxidizer (CatOx), and downstream, at the stack, to assess the destruction efficiency of the CatOx itself.

Methane emissions are at the center of the current climate crisis due to methane’s outsized contribution to global warming. Methane is one of the most potent greenhouse gases, being approximately 86 times more negatively impactful on climate change than carbon dioxide within the first 20 years in the atmosphere. It represents as much as 25% of the historic warming that can be attributed to human activities and is considered the greenhouse gas most responsible for driving warming in the near-term.

The Picarro G1101-i and G2101-i gas analyzers provide field measurements of the stable isotope ratio d13CO2 with a precision of 0.3 permil in five minutes. In an isotope ratio mass spectrometry (IRMS) laboratory, it is customary to dry the samples to very low dew points (< - 45C) prior to isotope analysis. For field work, however, drying the samples is in many cases inconvenient or impractical. Water vapor can affect the reported delta via spectroscopic broadening or direct spectroscopic interference.

Stable isotope analysis relies on the simultaneous or near-simultaneous measurement of two individual species. In the case of the Picarro G1101-i and G2101-i gas analyzers, these two species are 12C16O2 and 13C16O2, which we denote 12C and 13C for simplicity.

Picarro’s solution enables emissions data to be taken rapidly at scale. Emissions reductions are easily quantified for individual pipe replacement projects, individual leak repairs as well as across a network. Large emitters, which frequently contribute disproportionately to emissions reduction goals, can be easily identified so they are remediated first as part of an informed and cost-effective emission reduction strategy.

Utilities worldwide are using Picarro’s Asset Management Solution to further improve the choices they make regarding capital pipe replacement projects informed by traditional risk models. The Picarro solution combines data analytics with a vehicle-based methane emissions data collection platform to assist with capital replacement decisions. This leads to significant O&M cost savings through avoided leak repair by prioritizing replacements of pipelines with high leak densities. When this data is combined with traditional risk (DIMP) models, such benefits are maximized.

Picarro’s leak management solution leverages the power of data analytics to prioritize leak indications by potential risk.

No matter the regulatory environment, Picarro’s natural gas asset management solution enables natural gas distribution compliance that can be truly risk-based in its approach. A recent trend within the natural gas industry has been to increasingly take a risk-based approach to asset management, in this case, shifting schedules from periodic to being more driven by the particular risk profile of the infrastructure in a given localized area.

Picarro’s mobile leak detection solution – combining data analytics with an advanced vehicle-based methane emissions data collection platform – now allows natural gas leak plume data to be collected and interpreted at a speed and scale not previously possible. Further, advances in Big Data Analytics allow better-informed conclusions to be drawn from that data and enable improved decision making and outcomes.

Vaporized hydrogen peroxide (VHP) treatment is the dominant approach for decontamination in cleanrooms, restricted access barrier systems, and isolators, commonly a part of manufacturing operations for high-potency active pharmaceutical ingredients (HPAPI), large molecule drugs, and aseptic processing for dosage form fill and finish. Irrespective of the environment, decontamination is followed by an aeration cycle designed to ensure drug efficacy, safety, and stability, typically at levels well below 0.1 parts per million (ppm).
