Requires the use of specialized constant pressure piston sample bottles.
Requires specialized preparation and may be processed as either a liquid or solid sample.
Currently our lab processes gas samples in several ‘runs’ that analyze 43 separate components. Our equipment is capable of more but is limited to the specific standard lab-grade gases we keep for calibrating the chromatographs. Additional components can be added upon request.
We are currently using TRACE 1310 Analyzers made by ThermoFisher for both our Natural Gas and Natural Gas Liquid (NGL) samples. Each has multiple channels and utilize Flame Ionization (FID) to produce a detailed hydrocarbon chromatogram report. Total Sulfur is analyzed using a Flame Photometric Detector (FPD) on a separate channel.
Unless otherwise requested, we use the following analytical methods and values:
All analysis include the report, with the full analysis cost also including additional spreadsheets and formats for uploads into other systems. The raw data used to assemble the reports is also saved on the client’s data drive. This includes the actual chromatographs and each separate run.
Unless otherwise requested, we use 14.696 psia and 60.0 degF as our base pressure and temperature for calculations. Calculations that are provided by default for C6+, C14, and Full Analysis reports:
We currently have 300cc - 500cc gas sample bottles and constant pressure piston bottles (500cc). All our bottles are Sulfinert treated to maintain sulfur levels throughout the process.
All solid samples need to be completely dry prior to analysis. Any time needed for the lab to prepare the sample is shown on the rate sheet, however, only the time the technician uses is billed. For example, if the sample is dried in an oven for 6 hours, the oven time is not billable.
We use a Phenom XL SEM, upgraded with SED (secondary electron detector) and EDS (energy dispersive x-ray spectroscopy) manufactured by NanoScience Instruments. This allows samples of 100mm x 100mm to be viewed at 3 – 16x (Light) and 80 – 100,000x (Electron).
The EDS is an excellent tool to quickly identify and quantify individual elements within the solid sample. Specific areas can be targeted or larger areas can be mapped and color coded.
The SED collects low energy electrons from the top surface layer and reveals very detailed surface information. This is excellent for topography and morphology of corrosion coupons.
Most samples can be processed within an hour after they are prepared, resulting in an average total cost of $250.00 for analysis. The quick turnaround time and low cost makes EDS a viable alternative to X-Ray Diffraction. Keep in mind EDS provides the elemental breakdown, while XRD provides compounds.
Solid sample analysis includes the final report and pictures. Additional pictures and raw data information are also saved on the client’s data drive.
Generally, liquid and / or sludge samples require some preparation prior to analysis. This may include serial dilution, filtration, separation, etc. While there is a wide range of testing that can be completed, we typically categorize the analysis based on the client request.
General analysis includes items that could be completed in the field, but are also done in our lab.
- Dissolved CO2
- Dissolved H2S
- Presence of Water
- Specific Gravity
Our primary focus with Liquid / Sludge samples is with our Analyzers and Chromatographs. They are listed separately on the cost sheet for specific scenarios, but are typically done as part of a Full Analysis.
We use an iCAP 7400 Duo Analyzer installed by ThermoFisher Scientific for ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry). This has a wide range of applications and is used to determine the elemental breakdown of the sample with excellent detection limits. Items commonly requested:
- Barium, Boron, Calcium, Iron
- Magnesium, Manganese
- Phosphorus, Potassium
- Sodium, Strontium, Etc.
Ion Chromatography is done with Dionex Integrion HPIC Systems (ThermoFisher), with dedicated units set up specifically for Anions and Cations. Common examples include:
- Anion –
- Cation –
Bacteria inoculation is completed using serial dilution kits for SRBs (Sulfate Reducing Bacteria) and APBs (Acid Producing Bacteria). Results take 4-5 weeks, and this can be done separately or as part of a Full Analysis of the sample.
Additional items available as requested.
The majority of corrosion coupons we process are weight loss coupons. This is done in accordance with NACE SP0775 (latest version).
The coupons are photographed as received, chemically cleaned, and weighed to 0.00005g. They are visually reviewed for noticeable pitting and photographed again. Any coupons showing signs of pitting are further reviewed in our SEM to have the surface mapped and pit(s) measured.
Final reports include the weight loss, average corrosion rate, as well as the pitting rate (if applicable).
We are also capable of processing EM coupons, but this will require discussion and client direction on what constitutes an analysis. Estimated pricing is provided on the rate sheet and this is adjusted based on the requirements.
Photographs, lab notes, and calculations are saved with the final report on the client’s data drive.
We are often asked to complete other analysis that are not listed on any rate sheet. This may include pipe sample analysis (cut outs), soil samples, SEM photography, IC Programs, professional reviews and consultation of lab results, coating/paint analysis, etc. Costs for these items are specific to the project and typically require additional information to prepare a cost estimate.
Please contact us for more details.
We support an onsite data server that houses all of our analysis information. This server meets industry standard security requirements and is regularly backed up to offsite locations. Repeat customers are granted access to their specific data drive allowing real time access to view their results or review past results. Unless otherwise requested, clients have read/write access to their data drive.
We currently utilize an enterprise version of SynaMan (Synametrics File Manager) as software on our server to grant web based access to clients through https. This helps to alleviate any network security issues with connectivity on either side.
This is particularly well suited for clients who wish to keep databases or spreadsheets of results for historical trending. We can add the data to the databases or provide it in any format as requested. Clients can also upload their own historical data to be included.
There is no additional charge to our clients for server access.
We stock general materials like liquid sample bottles, testing equipment, corrosion coupons, bacteria kits, etc. Clients are welcome to purchase items we have or request orders of specific items. Pricing is generally based on our cost to have the item here and can fluctuate depending on the season or availability of the item in our stock.
