Real-time measurement of diacetyl in beerThe flavor of beer is strongly influenced by the presence of diacetyl and 2,3-pentanedione. Owlstone's Lonestar analyzer can detect and measure levels of these two vicinal diketones (VDKs) in minutes, right on the brewery floor. Offering detection down to 30ppb (parts per billion) and the ability to measure total diketones or free diacetyl, the instrument is ideal for early fermentation monitoring and finished product quality assurance.

Book Conservation Using Lonestar Portable AnalyzerAs stored books age they generate and release volatile organic compounds (VOCs). It has been shown that the release of certain emitted VOCs (such as furfural) is correlated to the extent of paper degradation in a book. The Lonestar portable gas analyzer can be used to detect VOCs associated with paper degradation and aid in the conservation of antique books, manuscripts and other paper based artifacts. |
 |
Detecting sulfites and SO2 using LonestarThe Lonestar portable analyzer is able to detect whether Traditional Chinese Medicines (TCM), herbal remedies and alternative medicine products contain sulphites by detecting the presence of trace amounts of sulfur dioxide (SO2). Sulfite sensitivity affects many people making the presence of sulfites in herbal medicines a common concern for consumers. |

Detecting potato rot with LonestarMaintaining the quality and health of stored potatoes is vital for growers, processors and consumers but each year there are consistent and substantial losses due to storage diseases. The Lonestar portable freshness monitor can detect volatile chemical signatures associated with bacterial diseases such as blackleg and potato soft-rot in real time. This allows the early detection and isolation of rotten potato stock, helping to prevent further losses. |

At Line Oil Assay with LonestarLonestar is a portable analytical platform that can provide detection and quantification of crude oil contaminants using Owlstone's award winning FAIMS technology. Lonestar can be used by non-specialists on site to rapidly analyse crude oil and feedstock samples for unwanted contaminants that can cause expensive down stream processing issues such as methanol, hydrogen sulfide stripping agents (triazines), MEA and organic chlorides. |
 |
Detection of Metaldehyde in Water Using LonestarLonestar offers rapid detection and monitoring of metaldehyde at concentrations low enough to meet the European and UK regulations for pesticides in drinking water. Lonestar can be operated on site by non-specialist personnel to monitor water for metaldehyde in only a matter of minutes. |
 |
Quality control of spices using LonestarThe Lonestar gas analyzer can be used to rapidly identify and measure the volatile essential oil content of spices such as cinnamon, cumin, ginger and cloves. With sampling taking only 10s of seconds, Lonestar offers a fast alternative to time consuming distillation methods for quality control. |
 |
Dimethyl sulfate gas detection using LonestarLonestar can be used as a dimethyl sulfate (DMSO4) gas monitor for ambient air. DMSO4 is a highly toxic but commonly used industrial methylating agent. Lonestar can continuously sample air and raise the alarm if the concentration of DMSO4 rises above a specified threshold level. |
 |
Rapid Screening of Plastic Bottles for dibasic estersThe Lonestar portable analyzer allows rapid detection of bottle rinse cleaning solvent DBE-3 (dibasic esters) and DMS (dimethyl sebacate) in PET (polyethylene terephthalate) beverage bottles and food containers at concentrations below 50 ppb, aiding compliance with FDA food contact notifications. |
 |
Validating Clean in Place Processes Using LonestarFast validation of Clean in Place (CIP) cycles by monitoring the composition of rinse water is vital to ensure adequate tank cleaning and for the optimisation of production processes in the food, beverage and pharmaceutical sectors. Lonestar delivers rapid, sensitive and accurate monitoring of rinse water helping to reduce water and cleaning product consumption. |

2,4 dichlorophenol in milk detection with LonestarLonestar is an easy to use and powerful analyzer for accurate, real time identification and monitoring of trace flavor contamination in milk including 2,4-dichlorophenol (DCP), 2,4-dibromophenol (DBP), biogenic amines such as triethylamine (TEA), milk adulterant benzoic acid and the milk age marker lactic acid. |
 |
Tribromoanisole Detection with LonestarLonestar is able to rapidly detect tribromoanisole (TBA) at concentrations as low as 10 ppt. TBA has been identified as a common contaminant in the pharmaceutical, food and wine industries. It has been cited by the FDA as a cause for concern and has been the reason for a number of product recalls. |
 |
Pharmaceutical waste water analysisWaste water treatment by bacteriological biodegradation is used to treat waste water streams (e.g. pharmaceutical, environmental bioremediation). Excesses of some solvents in the waste water can poison the microbes - reducing their efficiency. Consequently there is value in being able to quickly measure concentrations of these critical solvents so they can be pretreated/diluted to protect the bacteria. |
 |
Screening and age monitoring of edible oilsWithin the edible oils industry, Lonestar can offer at-line screening and monitoring of raw material contamination; flavor thresholds; preservative levels; fatty acid methyl esters; and residues from cleaning-in-place. |
 |
Food Freshness and Flavour MonitoringLonestar is an easy to use and powerful analyzer for food production and food safety compliance. The instrument can monitor freshness, flavours, taints or contamination in food and beverages. It detects aromas, essences and odour chemicals with high accuracy and sensitivity. Process monitoring with Lonestar can complement a HACCP or ISO 22000 approach to ensuring food safety and quality.

Oil Assay - Methanol AnalysisMethanol in crude oil impacts water treatment systems in refineries because bacteria involved in cleansing the water preferentially break down methanol, leaving hydrocarbons and toxins untreated. Methanol is miscible in water, so is present in the desalter effluent. Refineries often choose to cut crude runs rather than risk a "bug kill" - a large upset that would require major remediation and could cause violation of environmental legislation, permit exclusions or future penalties. |
 |
Propofol (2,6-diisopropylphenol) Anaesthetic DetectionPropofol (2,6-diisopropylphenol, a.k.a. Diprivan) is used as an intravenous general anaesthetic. Existing measurement techniques for IV anaesthetics require offline blood samples, making them unsuitable for monitoring anaesthetic depth and for ensuring patient safety. The Owlstone Lonestar Analyzer is able to detect propofol at sub part per billion concentrations in under 10 seconds. In addition, Lonestar is highly portable and can be operated by non-specialists. |
 |
Analysis of Scavengers for Sulfide (H2S) Removal from Crude OilTriazine compounds are commonly used as scavenger chemicals in crude oil to remove hydrogen sulfide H2S, in a process sometimes called "stripping". These triazine based additives are often present in excess of the levels required to prevent the H2S release, this excess and the by-products of the scavenging reaction with H2S, cause corrosion and fouling in downstream equipment. Consequently there is value in petroleum processors being able to quickly measure excess concentration of scavenger before custody transfer. |
 |
Rapid Detection of Geosmin, Fuels and Pesticides in Water SuppliesMonitor drinking water supplies to detect geosmin, fuel (diesel/gasoline/petrol), metaldehyde and other chemical contaminants. Using Lonestar analyzers, utilities can mitigate contamination incidents and avoid taste/odor complaints. Combat tightening regulations and terrorist threats, reduce the costs of supplying consumers, industry and food manufacturing. See the instrument work in the video. |

Real Time Identification and Monitoring of Trace ContaminationLonestar is an easy to use and powerful analyzer for accurate, real time identification and monitoring of trace contamination. Foods that contain muscle tissue (meat, poultry and fish) can form biological amines through enzymatic and bacterial actions of proteins and amino acids. For example, trimethylamine (TMA) is formed by a stepwise degradation of choline to betaine and then to TMA.
