Brand Numbers Resolution For Free

Rs = 1.5 is a "6-sigma" separation. Because +/- 3 sigma accounts for 99% of the area, that means that at Rs = 1.5, you have just less than 1% mutual overlap. In fact, Rs = 1.5 was originally called "99% baseline resolution". Over the years, the "99%" bit has been forgotten. -- Tom Jupille.

Hi-res images are at least 300 pixels per inch (ppi). This resolution makes for good print quality, and is pretty much a requirement for anything that you want hard copies of, especially to represent your brand or other important printed materials.

Resolution refers to the number of pixels in an image. Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image. For example, an image that is 2048 pixels wide and 1536 pixels high (2048 x 1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels).

A good selectivity for HPLC is 1.1, which allows a resolution of 1.5 to be achieved with about 10,000 theoretical places. The critical pair in a separation is defined as adjacent solutes that have the smallest 03b1 value.

+ Resolutions should ideally be 300 pixels per inch. + It's easier to start with a photo too large and size it down than to start with one too small and try to blow it up. + For print applications, your logo and line (clip) art should be vector files, not raster.

What DPI should your logo be? This is not always necessary when using an image online, but most will tell you that 72 DPI is the best.

Scientists consider a resolution of 1.0 or higher to represent an adequate separation. Measure the widths of two adjacent peaks in the chromatogram by noting where the x-axis values are at the base of each peak. The x-axis represents retention time, usually measured in seconds.
