Label-Free Screening of Drug–Protein Interactions by Time-Resolved Fourier Transform Infrared Spectroscopy

Screening for the interaction of small molecules with proteins is usually carried out by indirect methods by means of artificial labels or reporter systems. read more
Micro-ESR: Miniature Electron Spin Resonance Spectroscopy

Recent years have seen a dramatic upsurge in the availability of miniaturized sensing technologies. read more
Providing Purge Gas for FTIR Systems

While a Fourier transform infrared (FTIR) spectrophotometer provides a number of benefits relative to a scanning IR spectrophotometer,a significant disadvantage of an FTIR system is that the presence ... read more
Statistics in Analytical Chemistry: Part 14—Calibration Example 4

This fourth real-world example of calibration diagnostics comes from the same study as did Part 13 (American Laboratory, Sept 2004). read more
Statistics in Analytical Chemistry: Part 13—Calibration Example 3

Statistics in Analytical Chemistry: Part 10—Calibration Diagnostics (concluded)

This month's article will conclude the three-part series explaining calibration diagnostics. read more
Statistics in Analytical Chemistry: Part 9—Calibration Diagnostics (continued)

The previous article (American Laboratory, Nov 2003) introduced the subject of calibration diagnostics. read more
Statistics in Analytical Chemistry: Part 8—Calibration Diagnostics

The past seven articles have provided the fundamentals of calibration, including a protocol for designing a calibration study. read more
Statistics in Analytical Chemistry: Part 7—A Review

With the publication of the previous installment (American Laboratory, July 2003), this series of articles has arrived at a logical spot for reviewing what has been presented to date. read more
Statistics in Analytical Chemistry: Part 6—Calibration design

In the last installment in this series, it was suggested that a rule-of-thumb for calibration designs was five-by-five (i.e., five replicates of each of five concentrations), for a total of 25 data ... read more
Statistics in Analytical Chemistry: Part 5—Calibration: Calibration design

With many things in life, the quality and usefulness of the outcome depends in large measure on the care with which the event is planned. read more
Statistics in Analytical Chemistry: Part 4—Calibration: Uncertainty intervals

As was discussed in the previous column of this series (in the January 2003 issue of American Laboratory), calibration is a procedure that imperfectly transforms a response into a useful measurement. read more
The Determination of Toxic, Essential, and Nutritional Elements in Food Matrices Using an ICP-MS

The elemental and dynamic range of inductively coupled plasma-mass spectrometry (ICP-MS) makes it ideally suited for the analysis of food materials. read more
