Service Plan Agreements Introduced, Easing the Cost of Unbudgeted Repairs on Handheld XRF Analysers
Oxford Instruments (UK) has announced a series of comprehensive Service Plan Agreements for its handheld analysers enabling customers to protect their investment and eliminate unbudgeted service repairs. The Service Plan Agreements provide total peace of mind whilst maintaining maximum productivity.
With immediate effect, customers can benefit from Service Plan Agreements designed to fit with their differing business needs and individual budgets. The five different Service Plan Agreements cover the X-MET7000 Series of handheld XRF (X-Ray fluorescence) analysers, with up to 13 maintenance elements included.
Each plan option includes access to a global technical support helpdesk, an annual preventative maintenance schedule to retain measurement accuracy, plus an annual health and safety radiation and emission survey. Additional options can provide remote diagnostics, full parts and labour costs included in the event of a breakdown and equipment rental or loan.
For customers with a short term need for an X-MET7000 Series handheld XRF analyser and who prefer not to invest in a capital expense outlay, Oxford Instruments now offers a new global rental scheme. Customers can rent an analyser from one week at a time, or for up to six months.
Olaf Neuhausen, Global Service Director, commented, “We are aware of a change in the relationships between customers and suppliers. Customers are on the lookout for suppliers who genuinely strive to help them maximise productivity levels whilst minimising any risk of downtime from essential industry tools. Our Service Plan Agreement scheme is part of our commitment to support and add value to our customers business.”
Service Plan Agreements are quick and easy to setup and are available through a global network of distributors or by contacting Oxford Instruments OiService directly.
Featuring simple ‘point, shoot and analyse’, the handheld XRF analyser is used throughout a wide range of industry applications, ranging from PMI (Positive Material Identification) scrap and precious metals analysis through to mineral presence for mining and soils.

Setting the ASTM & EN Standards for Oily Residues Analysis in LPG by GC
To control the residue content during the LPG production, transportation or storage laboratories now have two global analysis standards at their disposal. One standard is the ASTM D7756-13 method for residues analysis in LPG by Gas Chromatography (GC) with the Liquefied Gas Injector (LGI). The latest standard is the harmonised EN 16423 method dedicated to the determination of residue in LPG with the LGI.
Both standards are based on direct, on-column LPG injection and use the innovative large volume injection technique developed by Da Vinci Laboratory Solutions (Netherlands). The technique was introduced in 2010 to inject liquefied Propane/Butane streams at room temperature directly onto a GC column and approved as ASTM D7756 in 2011.
The direct injection approach of the LGI includes the proven gasoline direct injection technique used by the automotive industry to inject fuel into the automotive engine combustion chamber. The LGI is configured on top of the GC and consists of a high pressure injection valve connected to an on-column needle.
The LGI pressure station and the GC enable a constant pressure of the liquid sample to inject a representative and repeatable amount of sample. The sample container is installed on the front side of the pressure station and is pressurised to 25 bar nitrogen. The waste sample is vapourised and vented to a central waste system. The controller box on top of the right side of the GC drives the injector valve timing.
In 2012 ASTM D7756 was revised to extend the application range of the method to the analysis of light contaminants such as benzene, toluene, C7-C10 hydrocarbons and DIPA in LPG. This summer ASTM published the 2013 revision for ASTM D7756 to include a full precision as a result of the first Round Robin conducted in 2012. The precision statement is also specified in the EN 16423 method.
The LGI offers laboratories a safe, fast and accurate GC method for the complex analysis of oily residues in C3 and C4 streams. Benefits include: GC alternative for the labour intensive ASTM D2158, EN 15470, EN 15471 & ISO 13757 methods; Approved as ASTM D7756-13 and EN 16423; No open air evaporation of LPG; High pressure injection directly onto GC column up to 30 bar; Analysis time < 30 minutes; Detection limits of <1 mg/kg for individual components; Flexible sample size, micro-second range up to 250 mS (large volume); Oily residue analysis range of 10 - 600 mg/kg.
For the petrochemical industry several new LGI applications are available for the trace analysis of DIPA in LPG and VCH, TBC and NMP in Butadiene. Read the full article from Petro Industry News to learn more about the LGI and its applications or visit the Da Vinci website to download the application notes.

Exceptional performance in design and manufacturing of process engineering sys- tems and pilot plants for the petrochemical industry.
To start measurement with the Analysette 22, select a predefined SOP (Standard Operating Procedure). The programme will prompt you to add your sample material. When the sample quantity is sufficient the measurement starts automatically – dispersion, analysis and report generation are also automatic.
Each Analysette 22 is delivered with the MaS control software containing the predefined SOPs for nearly all measurement tasks.
The SOPs can also be modified to suit your measurement requirements – the dispersion process and duration, measuring frequency, time intervals and many other parameters can be selected and saved as different SOPs.
Reports can also be freely edited, allowing you to organise your measurement results as needed. The report generator can incorporate graphs as well as measurement parameters, statistical values or selected measured values. These reports can also be integrated into local computer networks.
