Why Data Frequency Changes Everything Groundwater monitoring programs have traditionally relied on periodic sampling, such as quarterly, semi-annual, or annual data collection from wells. While this approach has been the industry standard for decades, it offers only a limited view of what is happening underground. Today, continuous monitoring is changing that paradigm. The difference ...

In highly regulated industries such as pharmaceuticals, biotechnology, and advanced manufacturing, contamination control is non-negotiable. Airborne particle monitoring plays a central role in ensuring cleanroom environments meet strict regulatory requirements like EU GMP Annex 1: 2022 and ISO 14644. One of the most effective tools for achieving continuous, reliable oversight is remote ...
Possible reasons: Graphite heating module aging or breakage Temperature sensor (thermocouple/RTD) calibration misalignment or damage Clogged ventilation system leads to poor heat dissipation Excessive sample volume or uneven bottom of container can lead to uneven heating. ...
In late 2013 newterra was contracted to design, build and rapidly deploy a modular and pre-manufactured 10 liter per second metals precipitation and solids removal system for a copper mine in Chile. Market Served Application Location Challenge Solution ...
The notebook and the used data can be found from our GitHub, which is linked at the bottom of this post! Loading sample data Let’s begin by looking at the data structure we have in a typical dataset. ...
While in top-down mass spectrometry (TD-MS)-based proteomics，intact proteins are directly separated and detected from the samples. As compared with bottom-up approaches, TD-MS is capable of providing more information on preserved protein species. ...
What is Contaminated Soil Sampling? Use of a proper contaminated soil sampling method is vital to obtain a representative sample of soil waste. A representative sample of soil waste is necessary to accurately characterize (hazardous or non-hazardous) your stabilized waste piles. If improperly conducted, valuable time and ...
In our last blog we provided a link to a case study on our website focussing on reducing the cost of condition monitoring programs, in particular oil analysis. ...
Materials and Method Set up in sites along the Baltic Sea coast of Schleswing-Holstein, Germany, thirteen stations took bi-weekly samplings for dissolved inorganic nutrient concentrations. Nine of these stations also continuously recorded temperature, salinity, and dissolved oxygen. All stations were located in boulder field or sandy bottom locations. To test ...
If things are not running…could it be someone pumped DEF into the fuel ...
I use the example of Boris the Strong-Man tapping a powder sample into a vial and the powder forms a near-solid puck. Then there is Gentle Jim, who gently taps the vial so that the powder flows to the bottom of the vial. ...

Cadmium is one of the readily volatile elements, therefore, it is important to observe proper measures to prevent loss of analyte at all stages from sampling to direct analysis. In particular, a sufficient temperature difference between the stages of pyrolysis and atomization should be ensured. ...
Sampling from tanks Take the sample from near the center and well clear of the bottom or the sides. ...
Bottom hypoxia and consequential hydrogen sulfide (H2S) release from sediment in eutrophic estuaries is a major global environmental issue. ...
Significant water quality differences were consistently observed among traditional parameters and pharmaceuticals collected from surface and bottom waters, which are rarely sampled during routine surface water quality assessments. ...
We estimated toxicity, cyto‐ and genotoxicity of bulk sediments from the Yenisei River in laboratory bioassay based on using several endpoints of aquatic plant Elodea canadensis (Elodea). The samples of bottom sediments (BS) were collected in the Yenisei River upstream and downstream of the sources of chemical and radioactive contamination. ...
Accordingly, methane concentrations at the bottom of the chamber were between 20 to 70% higher than those recorded at the middle or top sections of the chamber, regardless of fan position, fan air-flow strength or time before sample withdrawal. ...
Groundwater must be pumped from a certain sampling depth This sampling depth requirement is met hanging a dedicated stilling tube, say of 1/2 inch ID, in the well to the sampling depth. This tube may be supported by a hose clamp on the tube bearing on a hole in the well cap. Groundwater samples must be free of suspended ...
Flue gases were simultaneously sampled at the selective catalytic reduction (SCR) inlet, the SCR outlet, the electrostatic precipitator (ESP) outlet, and the stack. Samplings of coal, lime, bottom ash/slag, fly ash, and gypsum slurry were also conducted. ...
Nitrate retention within seep zones was evaluated over a 1-yr period (May 2002–2003) using a monthly, nested (top and bottom of seep) sampling approach along 15 individual seeps. Seep samples were analyzed for NO3–N, NH3–N, and dissolved organic carbon, along with stream waters and streamflow measurements at seven stream stations. ...
