We present LTE analysis of high resolution optical spectra for B-type hot PAGB stars LS IV-04 1 and LB3116 (LSE 237). The spectra of these high Galactic latitude stars were obtained with the 3.9-m Anglo-Australian Telescope (AAT) and the UCLES spectrograph. The standard 1D LTE analysis with line-blanketed LTE model atmospheres and spectral synthesis provided fundamental atmospheric parameters of T eff = 15 000±1000 K, log g = 2.5±0.2, ξ = 5.0±1.0 km s −1 , M/H = −1.81 dex, and v sin i = 5 km s −1 for LSIV-04 1 and T eff = 16 000±1000 K, log g = 2.5±0.1, v sin i = 25 km s −1 , and Fe/H = −0.93 dex for LB 3116. Chemical abundances of ten different elements were obtained. For LS IV-04 1, its derived model temperature contradicts with previous analysis results. The upper limits for its nitrogen and oxygen abundances were reported for the first time. The magnesium, silicon and calcium were overabundant (i.e. Mg/Fe = 0.8 dex, Si/Fe = 0.5 dex, Ca/Fe = 0.9 dex). With its metal-poor photosphere and V LSR ≈ 96 km s −1 , LSIV-04 1 is likely a population II star and most probably a PAGB star. LTE abundances of LB 3116 were reported for the first time. The spectrum of this helium rich star shows 0.9 dex enhancement in the nitrogen. The photosphere of the star is slightly deficient in Mg, Si, and S. (i.e. Mg/Fe = −0.2 dex, Si/Fe = −0.4 dex, S/Fe = −0.2 dex). The Al is slightly enhanced. The phosphorus is overabundant, i.e. P/Fe ≈ 1.7 ± 0.47 dex, hence LB3116 may be the first example of a PAGB star which is rich in phosphorus. With its high radial velocity (i.e. V LSR = 73 km s −1 ), and the deficiencies observed in C, Mg, Si, and S indicate that LB 3116 is likely a hot PAGB star at high galactic latitude.
