SYNOPSIS This paper provides the theoretic background for the measurement of TPH using MIR with RemScan. The potential as a rapid and accurate non-destructive method to determine TPH concentrations is proposed. The most sensitive parts of the IR spectra were investigated and identified. Provides background for selection of MIR DRIFT technique. Spectra are provided for […]
SYNOPSIS This paper investigates the effect on TPH remediation of co-contamination with lead on the efficacy of two bioremediation processes. The measurements were performed using RemScan and reference is made to the separate MethodsX paper for justification of accuracy. This paper demonstrates the usefulness of RemScan for research into bioremediation. View Paper Here
SYNOPSIS In this paper, Chevron companies discusses the requirement for rapid analysis of TPH. They then performed pilot studies to compare various types of field test equipment with laboratory by GC (USEPA 8015). It describes the pros and cons of each rapid method for field application. “The rapid, portable IR device (RemScan) provided TPH results

SYNOPSIS This paper provides a detailed comparison between RemScan and laboratory analysis, with specific reference to bioremediation test-work. The correlation coefficient (R2) between RemScan predictions and laboratory assays was 0.998. Measurements were taken over a range of samples with different soil types and a range of concentrations of 100-100,000 mg/kg TPH. RemScan provided a significant
SYNOPSIS This paper demonstrates that RemScan can be calibrated with high accuracy for very different soil types, a carbonate dominated clay from Padova region of Italy, a kaolinite dominated clay from north Western Australia and a loam from Nigeria. Correlation coefficients (R2) of 0.99 were routinely achieved. This shows that RemScan has the accuracy to
SYNOPSIS This is a general background paper talking about the fundamentals of measuring TPH using mid infrared and near infrared. It discusses the spectral peaks to use, the potential interferences, the effects of variations in soil texture and soil type and monitoring the degradation of hydrocarbons over time. It also compare the results of different

SYNOPSIS This paper explores the utilization of remote sensing, machine learning, and mid-infrared spectroscopy (MIR) in advancing Soil Organic Carbon (SOC) estimation. It presents compelling results, indicating a strong correlation (R² = 0.83) between MIR-based predictions and laboratory measurements. Additionally, it discusses the commercialization prospects of these technologies in Australia, with implications for sustainable agriculture and
SYNOPSIS The paper describes how Concawe University in the UK tested many of the commercially available TPH test kits in 2021. They found that RemScan provides: Decision-making results with a fast turnaround time and low cost per sample (Table 1 page V). Industry-leading sensitivity range of 0.1 to 100,000 mg/kg with excellent linearity and accuracy
SYNOPSIS This paper establishes the background for measurement of soil texture in the field using Ziltek’s portable mid-infrared instrument. It discusses how the results can be affected/degraded by presence of carbonate minerals, sample heterogeneity, varying analytical methods, sample particle size and moisture and the importance of minimising these effects.

SYNOPSIS Total Petroleum Hydrocarbons (TPH) in soil is often measured to determine if soils have been impacted by crude oil. PT. Chevron Pacific Indonesia (PT. CPI) operates several oil fields in Sumatra, and during site investigations and recovery, soil samples must be analyzed. Traditional laboratory methods require five days to complete, and commercial labs often
